Abstract
A simple low-resolution rapid-scanning infrared spectrophotometer has been developed from a modified commercial monochromator. When used with a cooled InSb or some other very fast response detector, this spectrometer is capable of over 20 000 scans per second, as limited by the present drive motor. A raster-type oscilloscope recording system is described which allows the photographic observation of many spectral scans on one oscilloscope. Sample emission spectra are shown of a xenon reflected shock and a xenon flash lamp.
