Title: Polarization optical device
Inventor: KASAMA NOBUYUKI
IPC: G02B5/30
Filed: 1995-03-07
Abstract: PURPOSE: To provide an inexpensive and small-sized polarization optical device by using a polarization element with a high P polarization component transmissivity (TP) and the polarization element with a low S polarization component transmissivity (TS) for a wave length and a luminous flux incident angle to the polarization element. CONSTITUTION: In incident white luminous flux radiated from a light source 101, a part of an S polarization component is transmitted through a first PBS(polarizing beam splitter) 102, but a P polarization component is hardly reflected to be transmitted through the PBS 102. The luminous flux consisting of almost only the S polarization component is projected to a second PBS 103, and almost all of the S polarization component is reflected, and the P polarization component is hardly reflected by the PBS 103 even if the TP is low to some extent. Then, the pure S polarization component is subjected to polarization component change by a light valve 104, etc., to be transmitted through the PBS 103 and only the P polarization component is transmitted through the PBS 103, and a high contrast image is obtained.  The luminous flux of the S polarization component subjected to no change by the valve 104 is almost reflected by the PBS 103 attached with importance to the TS component, and the image projected on a screen 106 becomes only the P polarization component, and high contrast is attained.
