Paper Abstract

A novel concept for video-rate parallel acquisition of optical coherence tomography imaging is presented based on in-pixel demodulation. The main restrictions for parallel detection such as data rate, power consumption, circuit size and poor sensitivity are overcome with a smart pixel architecture incorporating an offset compensation circuit, a synchronous sampling stage, programmable time averaging and random pixel accessing, allowing envelope and phase detection in large 1D and 2D arrays.
