Title: Projector and polarization converter
Inventor: YAMAUCHI YOSHITOSHI
IPC: G03B21/14
Filed: 2000-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a projector which eliminates the need for a complicated configuration making the apparatus heavier and in which flare can be eliminated and image contrast on the screen can be improved. SOLUTION: Concerning illuminating light of, for example, S-polarization, light consisting of three bands are bisected into a part of one band and a part of two bands by using a polarization filter 2 which converts only the part of the green G band into P-polarized light, and emits the remaining parts of blue B band and the red R band as they are as S-polarized light. The P-polarized light and S-polarized light are separated by polarization with a polarized light separating element 3. Furthermore, the components of the three bands are separated by performing, with a single dichroic film 4a, the band separation of the blue B band and the red R band which are the light of the same polarized component as S-polarized light.  By adopting this composition, it is made unnecessary to adopt a complicated configuration in which the dichroic films are crossing for separating the three bands simultaneously, the light of the three bands can be separated reliably with a simple configuration, and the problem of the flare is also overcome to yield a high-contrast projected image.
