16 October 1998 Signal-to-noise ratio analysis of the computed-tomography imaging spectrometer

We report results from a simple signal-to-noise analysis of the computed tomography imaging spectrometer (CTIS). The CTIS is non-scanning high-sped imaging spectrometer capable of simultaneously recording spatial and spectral information about dynamic events. This instrument is based on computed- tomography concepts and operates in the visible. The numerical estimate of the noise equivalent spectral radiance for the CTIS is 1.6 nanowatts per centimeter squared per steradian per micrometer.
