Zusammenfassung:	A system and method for the vibration suppression of a star simulation system by means of laser interference detection. The system for the vibration suppression of a star simulation system by means of laser interference detection comprises a laser light source (1), a first beam splitter (2), a collimating lens group (4), a second beam splitter (5), a reflector (6), a detection converging lens group (7), a CCD detector (8), a computer control system (9), a jitter compensation mirror (10) and a flat light splitter (11), wherein a light path of the entire system comprises a reference light path and a detection compensation signal light path. The reference light path and the detection compensation signal light path are simultaneously converged on the CCD detector (8) to form a vibration detection interference light path, and the computer control system (9) performs feedback compensation according to an intensity change in an interferogram formed by the vibration detection interference light path. The CCD detector
