Abstract:
The project explores laser scanners with Risley prisms using the novel graphical method that, to our knowledge, we have introduced for generating and studying easily (in contrast to complex analytical methods) their exact (not approximate) scan patterns. Risley prisms with two or three, rotational or oscillatory, simple or double prisms are studied analytically, graphically and experimentally. The main aim is to utilize them for Optical Coherence Tomography (OCT). Optical Path Difference calculus in the OCT interferometer, scan algorithms and driving solutions are developed, in a high risk, high gain approach. The advantage is to reach high scan speeds specific to Risley prisms, necessary for real-time in vivo OCT. The difficulty is to design their complicated scan patterns, solving issues such as non-linearity, speed, fill factor and image reconstruction. This approach is in competition with other’s efforts to pass from the precise (but slow) raster scanning to spiral and Lissajoux scanning, but with the slower galvoscanners or MEMS. Risley prisms are also compared with other scanners, e.g. polygonal. They are integrated in handheld probes in a new Swept Source OCT system built in the project. Biomedical and industrial OCT applications are targeted, especially in Dentistry and NDT. Validations are carried out using SEM, TEM, AFM and micro-CT. Collaborations include SC Inteliform-for prototypes; UMFVBT-for Dentistry, UoKent, UK and UoRochester, USA-for OCT; CUNY, USA-for MEMS

Abstract:
The project approaches a range of Optical Coherence Tomography (OCT) applications in Non-Destructive Testing (NDT)–in a partnership between The Coordinator (CO), 3OM Research Group (http://3om-group-optomechatronics.ro/), Aurel Vlaicu Univ. of Arad and The Partner (P), SC Inteliform SRL Timisoara, a SME specialized in Mechanical Engineering and Mechatronics. Knowing from previous projects the P’s necessities and technological requirements, the CO applies at P its demonstrated expertise in OCT for a range of NDT for several non-reflective materials (including plastics, composites, paint layers–for a variety of manufactured parts and technologies), for mechanical tools, and for metallic materials subjected to different mechanical processes (including milling, planning, wire-cutting). For the latter CO has demonstrated that OCT can replace the gold standard SEM in the study of metallic fractures and that it has the potential to replace in roughness measurements nowadays profilometer-based assessments. All OCT investigations are performed by CO with in-house developed Swept Source (SS) OCT systems (a functional one and another one to be developed in the project), Master-Slave (MS) enhanced, the latter patented by our main collaborator, Univ. of Kent (UK). Galvanometer- and MEMS-based handheld scanning probes for OCT developed in previous projects are implemented in manipulators–to be developed by CO, manufactured as prototypes by P, and to be demonstrated for OCT metrology for P. Other scanners, such as Risley prisms (patent application envisaged), as well as other scanning modalities (spiral and Lissajoux) than the common raster scanning are explored for OCT scanning in NDT. In-house developed polygon mirror-based SSs (telescope or telescope-less) are studied for the new OCT system developed in the project. Collaborations in the project include Univ. of Kent (UK), The Inst. of Optics, Univ. of Rochester (USA), and Victor Babes Univ. of Medicine and Pharmacy Timisoara.

Abstract:
The project performs a transfer of knowledge from the 3OM Group (http://3om-group-optomechatronics.ro/), Aurel Vlaicu Univ. of Arad, towards a SME focused on mechanical engineering and mechatronics, SC Inteliform SRL Timisoara. The scope of the project is to optimize the technological capabilities of Inteliform: electroerozion, manufacturing on machine-tools with CNC, thermal treatments and metrology – to achieve superior precisions, productivities and cost-effectiveness. These new performances will be verified through manufacturing components and mechatronic systems for a series of innovative products: optomechatronic choppers for the modulation of laser beams. The 3OM Group has obtained in this direction results recognized internationally through publications in journals in ISI Web of Science with an impact factor (IF) between 1.2 and 2.8, a patent and a patent application (prim inventor, the Principal Investigator (PI); co-authors, 2 researchers in the project). The optomechatronics choppers systems envisioned include, as rotational elements: (i) disks with windows with linear margins (articles IF 1.2 and 1.7); (ii) disks with semicircular margins or with shapes designed to obtain certain transmission functions (“eclipse” choppers, introduced by the PI in an article in CNCS, Elsevier, FI 2.8; 2016 patent; (iii) choppers with shafts with windows (2014 patent application). The rotational elements of the choppers are integrated in mechatronic systems with motors with control systems to stabilize rotational speeds at high values. The different chopper configurations are optimized for biomedical, optical metrology, and laser manufacturing applications. Both the rotational elements and the mechatronic systems of the choppers are introduced by the 3OM Group, through the project, in manufacturing at SC Inteliform SRL. Three postdocs, a PhD student, and three Master students are scheduled for internships at Inteliform to achieve these objectives.

Abstract:
The scope of the project is to demonstrate experimentally a plug-and-play Micro-Electro-Mechanical System (MEMS)-based handheld scanning probe for Optical Coherence Tomography (OCT) for a variety of in-house developed OCT systems: Time Domain (TD), Spectral Domain (SD), and Swept Source (SS). The Coordinator (CO), 3OM Research Group (http://3om-group-optomechatronics.ro/), Aurel Vlaicu Univ. of Arad, and its head, the Principal Investigator (PI), Prof. Duma have an internationally recognized expertise in laser scanners and handheld probes for OCT (through publications in journals indexed in ISI Web of Science with an impact factor (IF) from 1.34 to 3.49) that will be exploited to achieve distortion-free OCT imaging with such a prototype probe. So far there is only one study for such a MEMS-based probe, but for a particular technique, Gabor Domain Optical Coherence Microscopy (GD-OCM) achieved by The Institute of Optics, Univ. of Rochester, NY (#1 in Optics in USA), study in which the PI took part as Visiting Scientist, and which resulted in a paper published in Optics Express(IF 3.49) in June 2016. The challenge of this project is to develop such a probe that is universal, i.e. works with a variety of OCT systems, TD, SD, and SS; the latter two are faster than GD-OCM, therefore they are more adapted for real time, in vivo imaging. A working prototype will be built at SC Inteliform SRL Timisoara, a dynamic SME focused on mechatronics (https://erris.gov.ro/inteliform), and its functionality will be demonstrated at CO (https://erris.gov.ro/3OMGroup) in dentistry and in Non-Destructive Testing. For the former, two medical researchers from the Victor Babes Univ. of Medicine and Pharmacy of Timisoara and for the latter an expert from the Univ. of Kent, UK will be part of the CO team in the project – with access to both institutions’ infrastructures. Regarding MEMS, the head of the Nanofabrication Facility of the City Univ. of New York, NY, USA will be part of the CO team.

Abstract:
The present grant proposal involves 5 teams, led by the Optomechatronics Research Group (www.3omgroup.appspot.com/) of the Aurel Vlaicu University of Arad (CO). Two academic and clinical institutions are involved: Arad County University Hospital (partner P1) and University of Medicine and Pharmacy Victor Babes Timisoara, Faculty of Medical Dentistry (P3). A top company for medical analyses, SC Bioclinica SA (P2), leader in the field in Western Romania will provide histological feed-back for the imaging techniques to be developed, and it will apply, as well as P1 and P3, the OCT (Optical Coherence Tomography) systems and devices that will result from the project. A dynamic SME focused on precision mechanics, SC Inteliform SRL (P4) will manufacture the prototypes of the endoscope MEMS (Micro-Electro-Mechanical Systems) and of the handheld OCT probes, thus expanding its capabilities to micro-mechanics. The project comprises collaborative links on OCT with UoRochester, NY (where the PI was a Fulbright Senior on OCT, 2009-2010), UoKent, UK (where the PI is a Visiting Scholar, also on OCT), and with CUNY, NY (Nanofabrication Laboratory), on MEMS. Two Visiting scientists from the latter two institutions will be employed in the CO team for the summer time of each year of the project. The project objectives comprise: (i) The development of Swept Source (SS) and Spectral Domain (SD) OCT systems centered on different wavelengths, with high resolutions and fast acquisition speeds, suitable for imaging hard and soft tissue, for in vivo (but also ex vivo) medical investigations, in gastroenterology and colonoscopy, with P1 and P2, and in teeth, mouth, and materials for dentistry, with P3; (ii) The development of several OCT handheld and endoscope MEMS probes; (iii) A range of biomedical investigations in gastroenterology and dentistry; (iv) Treatments will also be approached by coupling aiming and treatment lasers through the OCT handheld and endoscope probes to be developed.

Abstract:
The project develops, based on a rigorous analysis we have achieved, new solutions and designing methods for scanners with rotating elements (polygon and monogon), respectively oscillatory (galvanometric). The designing calculus that is going to be developed using this analysis aims for the achievement of polygon scanners with simpler (therefore with lower costs) lens than the existing ones. The rotating element of the scanner is designed correlated with its lens, in order to compensate some of the essential sources of errors of the polygon. A particular case approached is the one of monogon scanners. Regarding the main classes of applications approached in the project, the dimensional measurements will be considered, as well as the polygon-based scanning filters for SS (swept source) OCT (optical coherence tomography), a hot topic for the optics community. In the domain of the galvanometer scanners we are working on a solution with an enhanced duty cycle (of up to 85-90%, with regard to 70%, the maximum value reached in present devices). Both 1-D (uni-dimensional) and a 2-D (bi-dimensional) devices will be studied, the latter one both for industrial applications (e.g., marking, welding), and for special ones, e.g. for the scanning modulus of confocal microscopes or for precise lateral scanning in OCT.
