摘要：In the paper, the control and calibration method on laser simulator is studied, which is based on optoelectronic confrontation hardware-in-loop (HWIL) simulation system. The control of the laser energy and spot size are necessary in the simulation system, and it is important to make the test successfully. The laser simulator simulates the changing of laser energy by the continuous rotation of Glan prism and the changing of the spot size by the telescope system. To get high accuracy of laser power and spot size, the accurate calibration of the relation of the rotation position and the attenuation process and the relation of spot size and the position of the motion platform in laser simulator is necessary. We apply dual calibration on the laser energy. In order to achieve precision simulation of spot diameter changes, we need to calibrate the relationship between four parameters accurately, they are the laser frequency, expansion beam lens's linear position, the distance of the receiver screen to the laser beam exit and spot diameter. And the feasibility was proved by the calibration data. © (2013) Trans Tech Publications, Switzerland.
