Abstract

This paper examines the relative significance of and dependencies between different noise sources which affect a sensor viewing a scene projector. An analysis is presented which compares the effect of various signal-dependent and signal-independent sensor noises, as well as the effect of projector nonuniformity (NU) on the sensor output. A key result of this analysis is a quantitative means to assess the importance of projector NU on sensor performance for different scene levels and operating conditions. It provides an analytical means to address questions such as: How and how much does projector NU influence the sensor response? At what level does the projector NU become a limiting factor in testing sensor performance? What is the penalty incurred in a particular test if a specified projector NU is not achieved? What effort should be expended to reduce projector NU in relation to other errors for a particular application? Discussion, results, and conclusions for a specific application are presented in addition to the analyses.
