Abstract
A novel charge coupled device (CCD) array enables the combination of imaging and semi-active laser (SAL) target designation to enhance seeker functionality at reduced inventory cost with lower collateral damage risk. The integration of SAL detection with imaging requires a high level of spatial and temporal resolution of the laser pulse detector and its correlation with the field of view of the imaging sensor so that laser spot location and code are presented with the image in real time. This evaluation of a novel SAL CCD detector concept shows that it is possible to achieve a temporal resolution in the region of 5μsec, an order of magnitude better than the basic requirement, and to achieve sensitivity to the laser pulse that allows operation in direct sunlight. The analysis indicates that the SAL CCD meets requirements using standard CCD processes. This paper reviews the detector architecture options and shows how the temporal, spatial and sensitivity requirements can be met.
