Abstract
This letter presents a passive wireless photo detector for precise localization of insects in biological studies. The detector is based on a photo diode matched to an antenna, and it produces modulated backscattering of microwaves when illuminated with amplitude modulated light. The radar cross section of the detector is derived and the concept is experimentally verified at 1.5 GHz.
