Abstract

An optical switch system and the system includes a semi-transmissive semi-reflective module is configured to intercept, in a transmission manner, test light that is the same as the signal light with respect to the propagation path and output after being modulated by the optical output control module; the imaging module is configured to acquire the test light, generate corresponding initial optical path information and sampled optical path information in sequence, and transfer the initial optical path information and the sampled optical path information to the judging module in sequence; the judging module is configured to record the initial optical path information, and compare the sampled optical path information with the initial optical path information; and the control module is configured to control the optical output control module according to a comparison result.
