Paper Abstract

The family of high spatial resolution (HSR) digital infrared imagers is described. The first generation, called the High Spatial Bandwidth (HSB) FLIR, was developed from the group of FLIRs known as the Class II Thermal Imaging Common Modules (TICM II), and provides improved horizontal resolution, a noninterlaced digital output suitable for interfacing to digital image processing, and a second output which can be tailored for most standard interlaced video formats. The HSB FLIR has been flown in several applications. The second generation of HSR FLIR, which is currently in production, provides expanded digital signal processing and improved sensitivity by incorporating a larger aperture scanner. Automatic control of temperature span and offset are provided, with implementation using field-proven algorithms suitable for accommodating very hot and very cold objects. The digital output conforms to the ATRWG 86-002 standard. Image processing features include zoom and pan, de-rotation, distortion removal, local image patch stabilization, overlays, convolutions, snapshot and frame storage, frame integration, analogue display of recorded digital data, and pseudo-color mapping.
