Paper Abstract

Miniaturized digital High Angular Resolution Laser Irradiation Detector (HARLIDTM) modules have been developed by the Defence Research Establishment Valcartier in collaboration with EG&G Optoelectronics Canada. These modules are designed to locate a collimated beam of radiation, such as a laser, within +/- 1 degree(s) over a 90 degree(s) field of view either in azimuth or elevation. There are presently two versions of HARLID: the 1-band HARLID which is based on Si detectors and is functional within the range of 0.45 to 1.1 micrometers ; and the 2-band HARLID based on Si/InGaAs detectors and is functional within the range of 0.45 to 1.70 micrometers . The principle of operation of this new patented module is based on the use of a Gray code mask to encode the angle of arrival of a laser beam. Military and civilian applications fields include defensive aid suites (Laser Warning Receivers) and platform guidance, alignment and positioning aids, where high angular precision is required. There are other laser detectors on the market, but HARLID has emerged, through laboratory testing and comparative field trials, to be one of the best performers, selling at the lower cost and having the lowest integration encumbrance.
