我们提出了不同的测试，模拟航空航天环境中的液晶可变延迟器（LCVR）在成像Magnetograph eExperiment postfocal仪器中使用的日出有效载荷在NASA的长期气球计划的光学效果。真空，温度，振动，伽马和紫外辐射的影响进行分析，通过测量这些测试的光学延迟，响应时间，波前畸变和透射率，包括一些原位测量的影响。还示出了LCVR的不同部分的放气测量。从获得的结果可以得出结论，这些光学设备是合适的，似乎是航空航天平台的优秀候选人。(c)2007年，美国光学学会。
We present the optical effects of different tests that simulate the aerospace environment on the liquid-crystal variable retarders (LCVRs) used in the Imaging Magnetograph eXperiment postfocal instrument of the SUNRISE payload within the NASA Long Duration Balloon program. Analysis of the influence of vacuum, temperature, vibration, and gamma and ultraviolet radiation is performed by measuring the effects of these tests on the optical retardance, the response time, the wavefront distortion, and the transmittance, including some in situ measurements. Outgassing measurements of the different parts of the LCVRs are also shown. From the results obtained it can be concluded that these optical devices are suitable and seem to be excellent candidates for aerospace platforms. (c) 2007 Optical Society of America.
