Electronic scanning spectrometer for measurements of rapidly changing spectra.
This spectrometer has a resolution of 15 A over the spectral region 0.6-1 micro, and can obtain electronically read out spectra at selectable scanning rates of up to 10,000 scans/sec. The technique of using an image dissector as the detector holds promise of even faster scan rates. The NEI of 4.6 x 10(-5) W/cm(2) at 0.8 micro is comparable with that of ir streak films. The instrument is ruggedized for field and airborne use.
