Abstract

The radiometric efficiency of a CCD Scanner with a fluorescent lamp is very poor due to the difficulty encountered in focusing the broad but relatively low radiance of the fluorescent source. Mirrors have been used to increase the efficiency, but the gain is not very high. The problem of using a mirror (or mirrors) is that the mirror cannot be placed at the most efficient position due to vignetting.
