Technical scheme and corresponding experiment for the PAT performance of a lasercom using an integrated test-bed

摘要

Recent successful demonstrations of laser communications have demonstrated the feasibility of some of the key aspects of this technology. The demonstrations can not success without the full-up ground test and validation So an integrate test-bed was build in build to test the technical parameters and to verify the working performance for the optical pointing, acquisition and tracking (PAT) of various inter-satellite lasercom terminals, In this paper, we detail the test technical scheme (TTS) and the corresponding experiments. The integrate test-bed is a high quality optical system that will measure the key characteristics of lasercom terminals, such as point error, tracking error, acquisition possibility etc. The test-bed can operate over the relative wavelength range.
