Abstract

A high-resolution single pixel camera for long range imaging in the short-wave infrared has been evaluated for the detection and localization of transient light flashes. The single pixel camera is based on an InGaAs photodiode with a digital micromirror device operating as a coded aperture. Images are reconstructed using compressed sensing theory, with Walsh-Hadamard pseudo-random measurement matrices and fast Walsh-Hadamard transform for localization. Our results from experiments with light flashes are presented and the potential use of the camera for muzzle flash detection and localization is discussed.
