Název v původním jazyce

Advanced InGaAs/InP single photon detector optimized for SLR and space debris optical tracking at 1 µm wavelength

Popis výsledku v původním jazyce

The newly optimized version of a single photon detector package based on commercially available InGaAs/InP was developed and tested for space applications including satellite laser ranging and orbiting space debris optical tracking. The detection chip can register photons in the wavelength range from 950 to 1100 nm, making the detector attractive for laser ranging at 1064 nm. The detector key parameters are detection delay, detection probability and timing resolution. All of these parameters remain stable up to 10 μs after the detector is gated. The timing resolution reaches below values of 60 ps rms. The long-term stability of the detector is better than 200 fs for averaging times of hours. This current detector version is suitable for space applications (namely SLR and space debris optical tracking) due to its sub-picosecond long-term detection delay stability and its single-shot precision of 1 cm in laser ranging.
