Proposal of a Single-Shot Multi-Frame Multi-Frequency CMOS ToF Sensor

A novel ToF image sensor architecture for simultaneously acquiring raw images at different modulation frequencies is introduced in this paper. The proposed approach constitutes a disruptive paradigm as it allows to obtain Fourier coefficients of the scene response function in a single-shot and free from harmonic distortion. Electrical simulations demonstrate the validity of the proposal.
Keywords: 3D image sensor, time-of-flight, single-shot, CMOS image sensor.
