First photon image
First-photon imaging may be of considerable value to both microscopy and remote sensing. The capture of three-dimensional (3D) structure and reflectivity using an active imager when the back-reflected optical flux reaching the detector approaches a few photons per pixel has many applications ( 1 – 3 ).
