摘要：Each reflective wall of two pairs of parallel reflective walls, which compose afour-wall reflection optical system, consists of three layers of a first dichroic mirror whichreflects blue light, a second dichroic mirror which reflects green light, and a third dichroicmirror which reflects red light. In the four-wall reflection optical system, the totalnumber of reflections varies according to the ratio of lengths of two pairs of the parallelreflective walls. For this reason, by selecting the number of reflections, it is possible toform an optical path of desired length and to color-separate the incident light into threerays of the three primary colors at desired separation intervals. A color scanner opticalsystem can easily be constructed by using the color separation optical system and a 3-line CCD.
