A first color beam is reflected by the first PBS unit, is reflected by a first light valve, and passes through the first PBS unit sequentially. A second color beam passes through the first PBS unit, is reflected by a second light valve, and is reflected by the first PBS unit sequentially. The dichroic unit is disposed on an optical path of the first and second color beams. The second PBS unit is capable of allowing a third color beam to travel to a third light valve and allowing the third color beam reflected from the third light valve to travel to the dichroic unit. The dichroic unit is capable of combining the first, second and third color beams.

The polarization beam splitter is disposed on the transmission path of the illumination beam between the illumination system and the first lens group. The polarization beam splitter permits the illumination beam to pass through and travel to the reflective light valve. The reflective light valve modulates the illumination beam to an image beam traveling to the polarization beam splitter. The polarization beam splitter reflects the image beam to the second lens group.

    摘要： A projection apparatus includes at least one light source, a field lens, a light valve, and a projection lens. The light source provides an illumination beam. The field lens is disposed in a transmission path of the illumination beam including an effective beam passing through the field lens and a ghost beam reflected by the field lens. The effective beam forms a light spot on the light valve capable of converting the effective beam into an image beam. The projection lens is disposed in a transmission path of the image beam and a ghost beam path of the ghost beam. A center of the light spot does not overlap a center of the light valve. An offset direction from the light valve to an optical axis of the projection lens is the same as a direction from the center of the light valve to the center of the light spot.
