Abstract
Single-Photon Avalanche Diode (SPAD) cameras are highly sensitive devices that detect individual photons, making them useful for low-light imaging. SPAD cameras are used for many active imaging applications such as LiDAR-a remote sensing technology that uses laser pulses to measure distances and create 3D models. The goal is to determine when the majority of photons arrive. The median photon arrival time helps in pinpointing that moment, providing information for constructing the 3D image. SPAD sensors experience a limitation called dead time—a brief period after detecting a photon when the sensor can not register another photon. To simulate dead times, we implemented a dead time masking function in the existing SPAD simulator code. This allowed us to investigate how dead time affects the perceived median photon count.
