Research of real-time control and calibration on laser energy simulator for optoelectronic confrontation HWIL system

In the paper, real-time control and calibration on laser energy simulator is studied, which is based on Optoelectronic confrontation hardware-in-loop (HWIL) simulation test system. The control of the laser energy is necessary in simulation system, and it is vital to make the test successfully. The laser energy simulator simulates the attenuation process and the changing of laser energy by the continuous rotation of Glan prism. To get high accuracy of laser power outdoor, the accurate calibration of the rotation position and the attenuation process in energy simulator is necessary. We apply dual calibration on the laser energy simulator, and the feasibility was proved by the calibration data.
