A low-cost add-on to commercial Fourier-transform spectrometers that have a continuously scanning Michelson interferometer has been developed for high-resolution, broadband, time-resolved spectroscopy. A number of innovations have been implemented to enable near-IR, visible, and UV photolumi-nescence studies. These include error correction and normalization of interferogram points to correct for laser intensity variations and missed shots, reduction of mirror-speed variations with recognition and avoidance of the timing mistakes they cause, and simple white-light-interferogram advancement optics that leave high-frequency modulation efficiency for the signal of interest unchanged in dynamically aligned systems. Application to energy-transfer phenomena in solid-state-laser media is described.
已开发出一种低成本的附加装置，用于配备连续扫描迈克尔逊干涉仪的商用傅里叶变换光谱仪，以进行高分辨率、宽带、时间分辨光谱学研究。已实施了多项创新技术，以实现近红外、可见光和紫外光致发光研究。这些创新包括干涉图点的误差校正和归一化，以校正激光强度变化和漏拍；通过识别和避免因镜速变化导致的定时错误来减少镜速变化；以及简单的白光干涉图推进光学器件，在动态对准系统中使感兴趣信号的高频调制效率保持不变。文中描述了该装置在固态激光介质能量转移现象研究中的应用。
