Analysis and Modeling for Thermal Focal Plane Arrays.
Abstract
The development of a first principles computer simulation of a generic pyroelectric thermal detector is described. 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 within a few percent. Performance estimates were made for conceptual several configurations and materials. Keywords include: Infrared; Thermal Detectors; Pyroelectric Detectors; Focal Plane Arrays; Computer Simulation; and Literature Survey.
