空间外差拉曼光谱仪（SHRS）的评估为stand-off拉曼测量在环境光条件下使用紫外（UV）和可见光脉冲激光与门控ICCD检测器。SHRS的宽接收角简化了光谱仪与望远镜的光学耦合，并且不需要精确的激光聚焦或激光在样品上的定位。如果激光束在样品上漂移或失去焦点，只要它在SHRS的视场内，拉曼信号仍然会被收集。SHRS对振动不太敏感，这些测量不需要振动隔离光学台。系统性能进行了评估，通过测量远离紫外和可见拉曼光谱的各种材料的距离高达18米，使用266 nm和532 nm的脉冲激光器，与12.4英寸。和3.8英寸。孔径望远镜，分别。
A spatial heterodyne Raman spectrometer (SHRS) is evaluated for stand-off Raman measurements in ambient light conditions using both ultraviolet (UV) and visible pulsed lasers with a gated ICCD detector. The wide acceptance angle of the SHRS simplifies optical coupling of the spectrometer to the telescope and does not require precise laser focusing or positioning of the laser on the sample. If the laser beam wanders or loses focus on the sample, as long as it is in the field of view of the SHRS, the Raman signal will still be collected. The SHRS is not overly susceptible to vibrations, and a vibration isolated optical table was not necessary for these measurements. The system performance was assessed by measuring stand-off UV and visible Raman spectra of a wide variety of materials at distances up to 18 m, using 266 nm and 532 nm pulsed lasers, with 12.4 in. and 3.8 in. aperture telescopes, respectively.
