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