Abstract:
The present invention provides a system (200) (300) (700) (800) and method for the reduction of speckle by applying a moving mirror (202) in the light engine of a projector. By imaging the mirror surface onto the entrance face of a multimode wave-guide (204), the beam enters the wave-guide (204) at a time -varying angle. When this wave-guide (204) is used to illuminate a display panel, the projected image on the wall has a time-varying speckle pattern. Since the period of the mirror is well below the integration time of the eye, a reduced speckle intensity is perceived. The use of the wave-guide (204) further reduces the speckle intensity due to mode scrambling.
Abstract:
The present invention provides a system (150) (160), apparatus (100) (200) and method to exploit the high beam quality of a laser light source to lower the cost and decrease the size of a color sequentially operated and laser based projector. Using a color mixing rod integrator (100) (200) (500) (550), laser light is homogenized, thus supplying the proper illumination pattern to a spatial light modulator. The rod integrator is also used to recombine the light of the primary colors, thus obviating dichroic recombination optics. For this purpose all light is coupled into the entrance plane of one and the same color mixing rod integrator. In this way a low cost and compact illumination system is obtained. By adding extra reflective layers to entrance (101) (201) and exit faces (105) of the integrator, the length of the integrator is decreased and/or the F/# in the system is increased. This enables a truly portable projector. When applying a color mixing rod integrator according to the present invention in a light engine with a reflective spatial light modulator, the integrator is very well suited for light recycling, which can increase an image's brightness up to a factor of three at average video display load.
Abstract:
In the color projector (200, 300, 400), a light source (220) produces first, second, and third colored light beams. An optical integrator (230, 330, 430) integrates the first colored light beam, the second colored light beam, and the third colored light beam. The integrated first colored light beam, second colored light beam, and third colored light beam are modulated by first (252), second (254), and third (256) light modulators, respectively, producing first, second, and third colored images. An optical synthesizer (260) combines the first, second, and third colored images to form a synthesized color image, and a projection lens (180) projects the synthesized color image. The optical integrator (230, 330, 430) includes a polarizing beam splitter (240, 441) in an optical path of at least one of the first, second, and third colored light beams to increase the effective integration length of the corresponding colored light beam.
