Paper Abstract

The development of a first principles computer simulation of a generic pyroelectric thermal detector is described. The formulation of the pertinent equations (based on a thorough literature survey) is presented. This simulation incorporates a finite difference treatment of the transient three-dimensional thermal response of composite focal plane arrays, with treatments of the signal generation, readout and processing, including all pertinent noise sources. A number of simplified problems having analytical solutions were treated to validate various portions of the simulation to generally much less than one percent in absolute temperature. Performance estimates were made for conceptualizing several configurations and materials. Results are given for the thermal crosstalk between adjacent detectors and the responsivities (for a Honeywell configuration) are compared well with Honeywell's predictions and measurements. Crosstalk predictions were within a few percent of Honeywell's while responsivities were within a factor of two. Reasons for these differences are discussed.
