Abstract

A high-performance hand-held thermal imaging camera has been developed, based on a 320×256-element InSb infrared focal plane array (FPA) operating in the medium-wave infrared region. The primary design objective was a low-cost, compact, lightweight, and portable thermal camera with a recognition range of 2 km. A staring FPA based on InSb technology with long and variable integration time provides the answer best suited to these requirements. The system provides such features as two-point and adaptive nonuniformity correction, bad-pixel detection and replacement, dynamic range compression, contrast and edge enhancement, histogram equalization, and digital scan conversion for CCIR-B-compatible output. The design methodology and the performance are presented.
