Book excerpt: This thesis presents the development of a CMOS smart imager for real-time optical coherency tomography (OCT). OCT, a measuring technique based on low-coherence interferometry, allows the acquisition of three-dimensional pictures of discontinuities in the refractive index of the sample. Due to the achieved depth resolution in the micrometer range, it has gained a lot of impact not only for many biomedical but also for industrial applications over the last few years. OCT allows the determination of surfaces as well as the acquisition of tomographic images of transparent and turbid objects with an outstanding depth resolution in the sub-micrometer scale over a depth range of up to several millimeters. The goal of this thesis was the realization of a very fast, robust 3D OCT system performing at close to the physical limit. A multi-channel approach has been chosen and a CMOS smart imager has been developed as they key component of the total system that includes an appropriate electrical, optical, and mechanical system. This system proves that by the use of parallel optical coherence tomography (pOCT) in combination with custom designed CMOS image sensors, real-time imaging with compact devices is realizable. For time domain (TD- ) OCT, the reference path length of the interferometer is varied and a simultaneous amplitude demodulation of the optical signal generates the depth image. The cross-sectional or volumetric image of a conventional TD-OCT system is generated by combining many laterally shifted one-dimensional depth scans throughout the object. Therefore, very fast reference path scanners and one or two translation stages are required. This results in a non-negligible mechanical system complexity. In pOCT, the translation scanners are replaced by image-forming optics and a two-dimensional image sensor. This step reduces the depth scan speed greatly and renders 3D image acquisition in some tens of milliseconds possible. On the other hand, the image sensor requiremen.
