Abstract

The development of miniature, light-duty and low power consumption satellite-borne new concept devices based on MOEMS has significant meaning to realize forming inter-satellite network and minimizing, integrating, intellectualizing the payload of satellite-borne laser communication system. Agile beam steering control system based on MOEMS can realize the large FOV, high precision, agile response trace and optical axis alignment for multiple targets in spatial optoelectronic system. Comparing to traditional technology, agile beam steering control system lower the volumes, reduce the weight and power. In this article, ANSYS thermal analysis software is used to simulate the thermal distortion of the micro-mirrors on the MOEMS. ZEMAX optical analysis software is used to simulate the outgoing beam before and after the distortion of the mirrors. Under certain conditions, high power laser beam will have thermal effect on the reflector based on the reflective MOEMS APT precise steering device. The simulation results show that: the thermal distortion of the micro-mirror is tiny when radiated by low power laser, the influence can be neglected. However, when the laser power increasing, the receiving power decreased, the system performance degraded. In order to mitigate the negative influence, relevant method must be adopted.
