Abstract
An display arrangement 16 comprises a two dimensional imaging array 3. Each column of the image array 3 is read sequentially by an electronic circuit 11. This energizes a one dimensional LED array 12 in dependence upon the received radiation. A motor 9 rotates a mirrored surface of a polygon 18 such that the image of the LED array is scanned. An observer viewing the LED array 12 via eyepiece 13 appears, due to persistence of visions, to see a complete image.
