摘要： A digital image projector includes an illumination-light source lamp and illumination beam forming optics for forming a white-spectrum illumination beam and color-band-separation optics to divide the illumination beam into color-component subbeams. The digital image projector also includes a reflective digital-image-encoding polarization modulator mechanism such as a reflective liquid crystal display polarization modulator to reflectively modulate the linearly polarized subbeams to form color-component image encoded-polarization subbeams and projection lens optics for projecting a color image divided from the image encoded-polarization subbeams. The digital image projector further includes a plate-supported, surface mounted fixed polarization-axis polarizing beamsplitter such as a wire-grid polarizing beamsplitter for dividing the color image from the image-encoded-polarization subbeams in which a polarizer support plate of the polarizing beamsplitter faces an illumination-source side of the optical system of the projector.
