Claims8
A viewing window for detecting radiation within a wide-angle region entering through the window, the viewing window comprising:
- a plurality of optical structures defining respective different individual prisms for receiving said radiation;
- said prisms being arranged in a planar array and defining respective entrance angles for said radiation with said angles being different for every viewing angle;
- detector means defining a plurality of discrete areas for receiving respective images thereon;
- and,
- a plurality of imaging units arranged behind respective ones of said prisms so as to permit each of said imaging units to image the prism corresponding thereto onto a selected one of said discrete areas.
