Paper Abstract

In this paper D* is analyzed as a figure of merit for focal plane arrays. Spatial noise (nonuniformity) is incorporated into the signal-to-noise ratio, and its effects are examined for a Schottky barrier and for a standard photon detector (constant quantum efficiency) over the 3 to 5 µm spectral band. The requirements for radiometric source uniformities are presented to show their effect in reduction of fixed-pattern noise. Because of the D* inadequacies presented in this paper, the preferred figure of merit is the signal-to-noise ratio.
