Photon Counting Module for Laser Time Transfer Space Project
Original language 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.
