A laser simulator is proposed which is based on a hardware-in-loop(HWIL) simulation test system.As an important device in the simulation test system,it is used to simulate the laser energy and the divergence angle.The laser simulator simulates the attenuation process of laser energy by the continuous rotation of Glan prisms and the changing of laser spot size through the continuous motion of the laser beam expanding telescope on the straight platform.The dynamic attenuation velocity of the laser simulator is up to 4 dB/s,and the divergence angle adjustment velocity is up to 3 mrad/s.The method is feasible for the simulation test.
