Abstract

Multi-pixel short-wave infra-red (SWIR) Geiger-mode avalanche photodiode (GmAPD) light detection and ranging (LIDAR) cameras have enabled unprecedented sensing capabilities in commercial and government platforms. Ball Aerospace develops and produces state-of-the-art SWIR synchronous and asynchronous single photon counting GmAPD arrays for variety of active and passive imaging applications. This work demonstrates the advantage of asynchronous arrays which is based on individual pixel continuous photon sampling functionality and the underlying read-out integrated circuit (ROIC). The benefit is based on user-selectable pixel hold-off (reset) time (tunable from ~250 ns to beyond ~5 µs) that determines aggregate pixel availability and noise performance. Single photon sensitivity and precise sub-nanosecond photon arrival timing for each pixel in the array enables advanced active and passive systems with unparalleled engagement ranges as well as novel imaging methods.
