Abstract

The principles of a technique for high-speed capture of infrared spectral information of radiation emission are described. The development of the technique has led to instrumentation which has been used in the laboratory and field for the analysis of such events as gun flashes. The optical design features allow the system to measure spectral characteristics up to 1000 times per second from targets at short or long observation ranges. The system has the capability of operation for multi-channeI high speed capture or steady-state radiation monitoring and hence provides a means for target/scene contrast assessment. Measurement data is presented together with an evaluation of signal to noise performance.
