Abstract
A single-photon avalanche diode (SPAD) detector includes a pixel array comprising multiple pixels and a memory operably connected to the pixel array. Each pixel includes a SPAD. Various techniques for accumulating signals received from the same SPAD over multiple scans and storing the accumulated signals in the memory are disclosed.
