摘要

针对液晶可调滤光器所处的空间热环境设计了热真空及高低温循环试验方案,旨在通过试验验证液晶可调滤光器在空间热环境下的器件光学性能。热环境试验的结果表明,液晶可调滤光器的光谱曲线较试验前仅漂移不超时0.1倍带宽,透过率降低不超过2%。为确保器件在空间温度环境下的性能更加可靠,又设计了液晶可调滤光器的热控改进方案,将工作温度控制在35±0.5 ℃。仿真结果表明LCTF器件经过合理的温控设计完全可以适应空间热环境。

Abstract

According to the space thermal environment of the LCTF, the sheme of thermal vacuum and temperature cycle experiment is designed. Through the experiment, the LCTF optical performance in spatial thermal environment can be tested. The experimental results show that the spectral curve of LCTF drifts no more than 0.1 times band width, and the transmittance decreases by no more than 2% comparing with before. In order to ensure the performance of the device in the space temperature environment more reliable, an improved thermal control scheme for LCTF is designed, and the operating temperature is controlled at 35±0.5 ℃. The simulation results show that the LCTF can adapt to the space thermal environment through reasonable temperature control design.
