Abstract

Time-resolved spectrometry was conducted in the mid-infrared region (2.8– 4.6 μ m ). A galvano-mirror causes a spectrally dispersed beam to repeatedly sweep up and down a PtSi focal plane array so that each element of the array is struck by the beam only once at some point within a time frame. Transient spectra of flowing gases (hydrocarbon and carbon dioxide) were measured at 80 μ s intervals.
