Abstract:

An experimental program has investigated the practicality of synchronized rotating filter wheels at the input and output of an image intensifier to produce a field-sequential color image. Both military and commercial intensifier tubes were used. Reasonably true-color rendition was obtained, even with the limitations imposed by crude equipment and far-from- optimum filters. Fundamental limitations result in rather large energy losses and hence preclude full-color operation at very low light levels such as starlight. At intermediate light levels, color viewing may be practical and may be valuable in enhancing target contrast. With appropriately chosen sets of input and output filters, the spectral response of camouflage detection film can be duplicated.
