Abstract
Disclosed in embodiments of the present invention are a synchronous control method and system for a laser test of an optical engine. The operation of a laser can be driven by the synchronous control system. When a test of a data point is finished and the optical engine stops for optical window cleaning, the laser may still maintain stable operation under the driving of the synchronous control system, experiments may be directly carried out next time, and thus, laser test efficiency of the optical engine can be improved. Moreover, the synchronous control system is adopted to independently drive the laser to achieve energy stability before experiments, preventing an influence of long-term operation on the performance of the optical engine, and improving test accuracy.
