ABSTRACT:
A light-sensing module and arrays of two or more light-sensing modules are described. Each light-sensing module comprises a mounting support structure that may include an air vehicle guidance section and an optical element adapted to direct incident light to a detector array that comprises an array of photodiodes and is attached to the mounting support structure. The detector array is adapted to receive the directed light and convert the received light to a set of electrical pulses via a plurality of photodetectors each of which is operatively coupled to an amplifier and a threshold circuit adapted to output a detection to a memory store adapted to associate a detection with a time-of-arrival. The light-sensing module may be adapted to output the associated detection and time-of-arrival. Air vehicles including the light-sensing modules are also disclosed.
