Photon Counting Module for Laser Time Transfer Space Project
Result description
We are presenting the results of research and development of the Single Photon Avalanche Detector (SPAD) for application in a Laser Time Transfer (LTT) space mission. For this joint project with the Shanghai Observatory, Academy of Sciences of China, wehave developed a detector package dedicated for the project of synchronizing the hydrogen masers based time scales by laser pulses. The technology demonstrator of a dual detector has been built and tested in our labs. The main parameters are: detection efficiency 10% at 532 nm, timing resolution 80 psec, dark count rate 8 kHz, non gated operation. The detectors active area is 25 um in diameter. The total mass, including bias stabilizing circuit, is 2 grams; the total power consumption is below 0.5 Wattper detecting channel.
