Abstract

The application of a Fabry–Perot etalon combined with an electron-optical image detector to obtain simultaneously time, spatial, and spectral resolution of plasma and laser sources is discussed, and comparison is made with oscillating Fabry–Perot interferometers. Matching of the interferometer to the image tube is considered, and optimum conditions are determined. Four types of image tubes were tested and the effects of signal-induced background and noise are described. Finally, the interpretation of time-resolved interferograms of wavetrains of very short duration, such as obtained from laser giant pulses, is dealt with, and extension of the interferometer spectral range in the vacuum uv reported.
