Abstract
Light in primary colors RGB modulated in a first modulation optical system is transmitted through a relay lens () and further divided into a P-polarized light and an S-polarized light by a PS separation wire grid (). The S-polarized light is transmitted through a wavelength spectral filter () to select red/green/blue light components R, G, Bof 615, 515, 450 nm in wavelength, which are then modulated by a Ydevice (). The P-polarized light is transmitted through a wavelength spectral filter () to select red/green/blue light components R, G, Bof 650, 550, 475 nm in wavelength, which are then modulated by a Ydevice (). The 3 -primary color lights modulated by the Y/Ydevices (), () are combined with each other at a PS composite wire grid () to project a synthetic light on a screen.
