Abstract
Recently developed Single-photon Avalanche Diode (SPAD) array cameras have single photon sensitivity and can provide time-of-flight information for LIDAR imaging. These SPAD cameras, however, have very few pixels and readout binary images, which are typically averaged to provide an image with sufficient dynamic range. Here, we propose to implement a modified version of Fourier ptychography (FP), a synthetic aperture technique, on SPAD cameras to reconstruct an image with much higher resolution and larger dynamic range from its binary measurements. We successfully validate this using simulated and experimental results to show its potential for recording LIDAR images at high resolution and speed.
