Recently developed single-photon avalanche diode(SPAD)array cameras provide single-photon sensitivity and picosecond-scale time gating for time-of-flight measurements,with applications in LIDAR and fluorescence life-time *** compared to standard image sensors,SPAD arrays typically return binary intensity measurements with photon time-of-arrival information from fewer ***,we study the feasibility of implementing Fourier ptychography(FP),a synthetic aperture imaging technique,with SPAD array cameras to reconstruct an image with higher resolution and larger dynamic range from acquired binary intensity *** achieving this goal,we present(1)an improved FP reconstruction algorithm that accounts for discretization and limited bit depth of the detected light intensity by image sensors,and(2)an illumination angle-dependent source brightness adaptation strategy,which is ***,these provide a high-quality amplitude and phase object reconstruction,not only from binary SPAD array intensity measurements,but also from alternative low-dynamic-range images,as demonstrated by our simulations and proof-of-concept experiments.
