Abstract: An optical system capable of outputting hi-contrast images and multi-primary color or 3-dimensional images is provided. Light in primary colors RGB modulated in a first modulation optical system is transmitted through a relay lens 36 and further divided into a P-polarized light and an S-polarized light by a PS separation wire grid 37. The S-polarized light is transmitted through a wavelength spectral filter 39 to select red/green/blue light components R1, G1, B1 of 615, 515, 450 nm in wavelength, which are then modulated by a Y1 device 44. The P-polarized light is transmitted through a wavelength spectral filter 46 to select red/green/blue light components R2, G2, B2 of 650, 550, 475 nm in wavelength, which are then modulated by a Y2 device 51. The 3-primary color lights modulated by the Y1/Y2 devices 44, 51 are combined with each other at a PS composite wire grid 55 to project a synthetic light on a screen.
