چکیده
Abstract Integrating all optical components of an coherence tomography (OCT) device into a single chip is non-trivial and challenging job. The design development such lab-on-a possible only via Micro-Opto-Electro-Mechanical System (MOEMS) technology. reproducible integrated fabrication would reduce cost size many folds as compared to bulk or fiber optic OCT system. A miniaturized less than 5mm 2 area designed, simulated, optimized. successful this help in point-of-contact devices well embedded biomedical sensor applications. Also, the promises possibility chip.

Optical coherence tomography by all-optical MEMS fiber endoscope
This paper presents the first successful demonstration of all-optical MEMS (microelectromechanical system) fiber endoscope for OCT (optical coherence tomography) measurement. A MEMS optical scanner for spatial light modulation has been assembled in the endoscope probe head (φ 6mm) with optical components and a photovoltaic cell. Actuation energy for the MEMS scanner is optically supplied by usi...
متن کاملParallel optical coherence tomography system.
We present the design and procedures for implementing a parallel optical coherence tomography (POCT) imaging system that can be adapted to an endoscopic format. The POCT system consists of a single mode fiber (SMF) array with multiple reduced diameter (15 microm) SMFs in the sample arm with 15 microm center spacing between fibers. The size of the array determines the size of the transverse imag...
متن کاملIntegrated intravascular optical coherence tomography ultrasound imaging system.
We report on a dual-modality optical coherence tomography (OCT) ultrasound (US) system for intravascular imaging. To the best of our knowledge, we have developed the first integrated OCT-US probe that combines OCT optical components with an US transducer. The OCT optical components mainly consist of a single-mode fiber, a gradient index lens for light-beam focusing, and a right-angled prism for...
متن کاملTowards Integrated Optical Coherence Tomography System on Silicon on Insulator
Optical Coherence Tomography (OCT) is an emerging optical imaging technology with ever growing number of applications. OCT enables micron scale cross-sectional imaging of subsurface microstructures by measuring the backscattered intensity of light from subsurface layers of the materials. Current OCT imaging systems are fiber or free space optics based and they can be miniaturized through integr...
