Abstract
The design and preliminary evaluation of a low cost video based multispectral camera system developed in the Standoff Mine Detection Ground (SMDG) exploratory development project for the US Marine Corps is described. The system is composed of an intensified and gated video camera fitted with six user selectable filters in a synchronous spinning filter wheel which provides a different spectral filter for each video frame. The camera system is microprocessor controlled for automatic exposure and matched with custom designed spectrally corrected optics. The associated analog and digital image storage and processing equipment and techniques are also discussed. This system has been field tested to detect land mines at long standoff distances.
