摘要： Red, green, and blue laser light emitted from laser light sources 1-3 is transformed into substantially parallel beams by collimator lenses 4-6, collected by microlens arrays 7-9, and rendered uniform by rod integrators 10-12, whereupon it is used to illuminate spatial light modulation elements 16-18 and subjected to modulation. The modulated laser light exiting from the spatial light modulation elements 16-18 is recombined using a beam-combining prism 19 and subjected to pixel separation using a birefringent plate 20, which is rotationally driven by a birefringent plate rotary drive unit 26, after which it is projected upon a screen 22 using a projection optical system 21. The birefringent plate 20 spatially separates the modulated laser light using birefringence. When pixels are spatially separated by the birefringent plate, the pixel grid region is made smaller, the distribution of brightness on the screen is rendered uniform, and speckle noise is reduced.

摘要： An illumination apparatus includes a light source (1), a first integrator (11) into which light from the light source (1) enters, and a second integrator (33) into which light exiting from the first integrator (11) enters. Accordingly, the aperture shape of the first integrator (11) can be optimally designed, so that the light utilization efficiency can be increased. Furthermore, even when the length of the first integrator (11) is reduced, a deficiency in the light uniformity due to the first integrator (11) is compensated for by the second integrator (33), so that high uniformity can be secured at the surface to be illuminated.

摘要： A device includes a light source 1, a reflection-type light valve 9 that controls a traveling direction of exiting light based on an input signal, an illumination optical system 2, 3, 4, 6a that focuses light from the light source on the reflection-type light valve as illumination light, a projection lens 10 that projects exiting light from the reflection-type light valve, a first diaphragm 7 provided at a position of a pupil of the illumination optical system so as to block a part of the light from the light source, and a second diaphragm 8 provided at a position of the pupil of the projection lens so as to block a part of the exiting light from the reflection-type light valve. A part of the illumination light reflected from a surface of the reflection-type light valve to be incident on a pupil of the projection lens as unnecessary light is blocked by a combination of the first diaphragm and the second diaphragm. The light shielding region of the first diaphragm corresponds to a divided region on an outer peripheral side between divided regions obtained by dividing the region of the pupil of the illumination optical system corresponding to the range of the unnecessary light by a line in a chord direction, and a light shielding region of the second diaphragm is shaped and arranged so as to correspond to the divided region on a center side. The unnecessary light incident on the projection lens is blocked efficiently, thereby achieving high brightness performance.
