摘要： Briefly, in accordance with one or more embodiments, a buried numerical aperture expander (100) may be utilized to provide a head-up or virtual display at a larger field of view without requiring a larger amount of space, larger sized display, or larger sized optics. The buried numerical aperture expander is capable of selectively reflecting light emanating from a display such that the reflected light is expanded into a larger field of view, while simultaneously allowing other light to be transmitted through the buried numerical aperture expander without expansion so that the buried numerical aperture expander may be deployed in conjunction with a windshield or window without adversely affecting the ability to see through buried numerical aperture expander.
摘要翻译：简而言之，根据一个或多个实施例，可以利用埋藏的数值孔径扩展器（100）来提供更大的视野的平视或虚拟显示器，而不需要更大的空间量，更大尺寸的显示器或更大的尺寸大小的光学。掩埋式数值孔径扩展器能够选择性地反射从显示器发出的光，使得反射光扩展成更大的视野，同时允许其他光透过埋入的数值孔径扩展器而不膨胀，使得掩埋的数值孔径扩张器可以与挡风玻璃或窗户一起部署，而不会不利地影响通过掩埋的数值孔径扩展器观察的能力。

摘要： An image generation apparatus (100) provides correction for color offsets. Color offsets may be caused by misalignments in laser diodes or optics assemblies in a laser projector. The offsets may be measured during or after manufacture of the laser projector. An image buffer (112) is responsive to the offset data to translate each color plane separately. The image buffer may include separately addressable portions for each color. Further, variable delay elements on the output of the image buffer may provide color offset correction. Interpolation provides further offset correction.
摘要翻译：图像生成装置（100）提供彩色偏移的校正。颜色偏移可能是由于激光二极管或激光投影机中的光学组件中的未对准引起的。可以在制造激光投影仪期间或之后测量偏移。图像缓冲器（112）响应于偏移数据以分别转换每个色平面。图像缓冲器可以包括用于每种颜色的单独可寻址部分。此外，图像缓冲器的输出上的可变延迟元件可以提供颜色偏移校正。内插提供进一步的偏移校正。

摘要： An imaging system (300) configured to reduce perceived flicker in three-dimensional images is provided. The imaging system (300) can include a plurality of light sources (305,306,307), a light combiner (302), a light modulator (303) and a polarization rotator (301). The light combiner (302) combines light received from each of the light sources into a combined beam (304). A first light portion (313) in the combined beam has a first light portion polarization state that is different from a second light portion polarization state of a second light portion (314). The light modulator (303) produces images by modulating the combined beam (304) along a projection surface (316). The polarization rotator (301) selectively rotates a polarization state of the combined beam (304) in synchrony with an image refresh cycle of the imaging system. A circular polarizer (1004) can be used to transform linear polarization states to circular polarization states.

摘要： A laser-based imaging system (200) is configured to reduce perceived speckle in images (201). The imaging system (200) includes one or more laser sources (207), a light modulator (204) configured to produce the images (201) with light (205) from the laser sources (207), and one or more active polarization switches (206) disposed in an optical path of the imaging system (200). The active polarization switch (206) is configured to alternate a polarization orientation of the light in synchrony with an image refresh cycle of the system. The active polarization switch can be clocked in accordance with a clocking angle to optimize speckle reduction. Additionally, one or more light preconditioners (991,992) may be used to help optimize speckle reduction.

摘要： 3D Modeling System and Apparatus for mobile devices with limited processing capability is disclosed. This invention uses the standard camera and computing resources available on consumer mobile devices such as smart phones. A light projector (e.g. laser line generator) is attached as an accessory to the mobile device or built as a part of the mobile device. Processing requirements are significantly reduced by including known object(s) or reference template(s) in the scene to be captured which are used to determine the pose/position of the camera relative to the object or scene to be modeled in a series of camera pose/position sequences. The position/pose of the camera and projector for each sequence is facilitated by image distortions of known dimensions of reference template or known object in a sequence of captured images.
