红外折射计 infrared refractometer
快速折射红外光学系统 fast refractive infrared optical system
红外线的折射 Refraction of Infrared
在这个距离，恒星的光源光被折射，或拉伸成红外波长，在外层空间只有斯皮策太空望远镜才能观测到。
At this distance the optical light from stars is shifted, or stretched, to infrared wavelengths that can only be observed in outer space by Spitzer.
作为长波红外低折射率材料，这几种材料在将来都有应用潜力。
All of these materials will be the potential long wavelength infrared low refractive index materials in the future.
利用有限元分析结果，根据热光效应和弹光效应理论，对气动热环境下红外光学头罩的折射率场进行数值计算。
Based on the theories of thermo-optical effect and elastic-optical effect, the refractive index field of the dome was numerically computed with the result of the finite element analysis.
