Abstract: The Radiometry I Branch, Optics Division, U.S. Naval Research Laboratory, has been engaged for a number of years in research on rapidly occurring phenomena. Most of the work was performed as part of a project initiated and supported by the Los Alamos Scientific Laboratory of the University of California. The spectroscopic phase of this work required the development of many unusual dynamic high-speed spectrographs having a wide variety of time resolutions, wavelength resolutions and wavelength coverages. There are three general types of time-resolving spectrographs: (1) moving-film, (2) rotating-drum and (3) rotating-mirror. Two moving-film-type instruments were developed: the f/6.6 Cine High-Speed Prism Spectrograph produces 4,600 framed low-dispersion spectra per second for the ultraviolet and visible regions; and the N4GS f/2.8 Grating Spectrograph, modified from the Cine, produces low-dispersion streak spectrograms in the visible region. The maximum time resolution of the latter instrument is 1.0 μsec. The Mk55 High-Speed Ultraviolet Spectrograph is a rotating-drum medium-dispersion instrument with a time resolution of 0.1 μsec. It was designed and built for NRL by the University of Rochester. The f/6.6 102 Prism Streak and the f/6.6 N9GS Grating Spectrographs are rotating-mirror-type instruments. The 102 is a low-dispersion instrument for the ultraviolet and visible regions and the N9GS is a high-dispersion spectrograph for the same regions. Both of these spectrographs have a maximum time resolution of 0.01 μsec.
