Development of an Indium Gallium Arsenide (InGaAs) Short Wave Infrared (SWIR) Line Scan Imaging System

Abstract

This report describes the design, operation, and performance of a line scan imaging system using a one-dimensional (1-D) 256 indium gallium arsenide (InGaAs) photodiode linear array sensor that operates in the short wave infrared (SWIR) (0.8 1.7um) region. The system provides temporal profile images that show the outline, shape, size, height, and grey-shades of moving objects at a distance. These profile images allow low bandwidth and low power operation for detection and easy identification of human and nonhuman objects. The system is suitable for various covert Intelligence, Surveillance and Reconnaissance (ISR) operations in military or border security environments. It is inexpensive, estimated to be about 10 20% of what a regular two-dimensional (2-D) SWIR imaging system costs.
