The interferogram equations for a Michelson interferometer operated with a mosaic array of detectors are derived. The effects on the instrumental line shape function (ILF) due to an individual detector field subtense and its displacement from the optical axis of the interferometer have been numerically computed from the interferogram equations. Theoretical predictions of the dependence of the ILF on various system parameters are presented as well as comparisons of the theoretical ILF with those measured in the laboratory.
