Photon Counting Detectors Based on InGaAs/InP for Space Objects Laser Ranging

Roberta Bimbová, Ivan Procházka, Jan Kodet, Josef Blažej

We have developed photon counting detectors based on InGaAs/InP SPAD for space object laser ranging. Two key versions of detector control electronics were developed, tested, and compared: passive quenching and active quenching. The key parameters of these two photon-counting detector versions were …
