A study on a new ranging camera operating on the Time-of-Flight principle using 870nm active illumination is presented. The key component of this camera is a sensor comprised of 120x90 pixels based on a Current Assisted Photonic Demodulator (CAPD), implemented in standard CMOS 0.35um technology. The resulting camera system is capable of providing real-time accurate depth maps of the scene. An analysis was performed of the systematic noise of obtained depth map under various conditions. Measurement results with different modulation frequencies are presented showing non- linearities over the frequency range. In conclusion a compensation technique is proposed.
