Abstract
A flat-panel camera comprises a tapered transparent slab 1, a prismatic sheet 3 for introducing light into one face of the slab at near the critical angle so that it is reflected along the slab towards the thick end, and a miniature camera 2 receiving light emerging from the thick end of the slab at an angle depending on where the light entered the slab. An image processor 7 eliminates distortion in the image such as gaps caused by the light missing the camera.
