Paper Abstract

A miniaturized digital 1-band HARLID module using linear silicon detector arrays has been developed. These HARLID modules, which fit inside standard TO-8 packages, were designed to locate angularly a pulsed laser source within plus or minus 1 degree over a 90 degree field of view either in azimuth or elevation. The principle of operation of this new patented-module is based on the use of a Gray code ask to encode the angle of arrival of a laser beam. The electro- optical (E-O) performance of this new module has been evaluated in the laboratory. A laser warning receiver (LWR) demonstrator integrating two of these modules has been built and its E-O performance measured in the laboratory and in a field environment aboard a tank. A new 2-band HARLID module now under development will include a sandwich of Si and InGaAs detector arrays and will extend the spectral band of the HARLID from 0.4 to 1.7 micron while increasing significantly its responsivity at 1.064 micrometer. A study of its technical characteristics and limitations has been recently completed and future HARLID technology development plan established.
