    摘要: An integrating rod (100) for combining light beams from two or more sources. A first light beam (104) enters the integrating rod 100 through a first entrance face (102) to a first reflecting face (110). The light is reflected by the first reflecting face (110) and travels along the major axis (114) of the integrating rod (100) to an exit face (116). A second light beam (108) from a second light source enters the integrating rod (100) through a second entrance face (106). The second light beam may be reflected by a second reflecting face (112) and travels along the major axis (114) to the exit face (116). The two light beams experience multiple reflections as they travel along the integrating rod and leave the integrating rod (100) through the exit face (116) as a single homogenous light beam.

    摘要: A pulse driven two lamp (40, 50) single light valve (62) imaging display system (10). The first lamp (40) is used to generate red light, and the second lamp (50) is used to generate blue and green light. A beam splitter (46) combines the white light of the two light sources, and directs the light to a color wheel (26). The first red lamp (40) is driven at a peak power being 3X the average power rating of the lamp for ⅓ of a video frame. The second blue-green lamp (50) is pulse driven at a peak power being 150% its average power rating for ⅔ of a video frame. The present invention achieves improved color balance and increased intensity, and is a simple and cost effective architecture.

    摘要: System and method for reducing visible speckle in images displayed using coherent light. An embodiment comprises a first layer in a light path of a display plane, the first layer collimates and diffuses light passing through the first layer from a light source side of the display plane along the light path, an actuator coupled to the first layer, the actuator moves the first layer in plane orthogonal to the light path, and a second layer in the light path on a viewing side of the display plane, the second layer increases a viewing angle of the display plane. The actuator continuously moves the first layer so that the light passing through the first layer is diffused to reduce the appearance of speckles.

    摘要: Device and method for an antireflective coating to improve image quality in an image display system. A preferred embodiment comprises a first high refractive index layer overlying a reflective surface of an integrated circuit, a first low refractive index layer overlying the first high refractive index layer, a second high refractive index layer overlying the first low refractive index layer, and a second low refractive index layer overlying the second high refractive index layer. The alternating layers of high refractive index material and low refractive index material form an optical trap, allowing light to readily pass through in one direction, but not so easily in a reverse direction. The dual alternating layer topology improves the antireflective properties of the antireflective layer and permits a wide range of adjustments for manipulating reflectivity and color point.

    摘要: A micromirror device having an array of mirrors 802 formed with a jagged leading 804 and trailing 806 edge. The jagged leading and trailing edges eliminate the features that cause the most diffraction-straight edges that are perpendicular to the incident illumination 808. The leading and trailing edges preferably are formed as a series of saw teeth having a 45° angle to the incident illumination 808. Angling the edges relative to the illumination axis greatly reduces the diffraction that would occur from edges perpendicular to the illumination axis. By reducing the diffraction, the jagged leading and trailing edges enable the use of orthogonal illumination which reduces the cost, size, and weight of the associated TIR prism. The number of saw teeth can vary, but the three-tooth pattern provides an optimum mixture of low diffraction and ease of production.
