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.

摘要： An image capture system for an image data capture and processing system, consisting of a digital imaging device, active illumination source, computer and software that generates 2 dimensional data sets from which real world coordinate information with planarity, scale, aspect, and innate dimensional qualities can be extracted from the captured image in order to transform the image data into other geometric perspectives and to extract real dimensional data from the imaged objects. The image transformations may be homographic transformations, orthographic transformations, perspective transformations, or other transformations that takes into account distortions in the captured image caused by the camera angle.

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 optical apparatus (201) for use in an laser imaging system (200) is provided. The optical apparatus (201) includes one or more optical elements (215) that are configured to create an intermediate image plane (217) in the laser imaging system (200). A diffractive optical element (216) is then disposed at the intermediate image plane (217) to reduce speckle. The diffractive optical element (216) includes a periodically repeating phase mask (218) that can be configured in accordance with steps, vortex functions, Hermite-Gaussian functions, and so forth. Smooth grey-level phase transitional surface (337) can be placed between elements (333,334) to improve brightness and image quality. The periodically repeating phase mask (218) makes manufacture simple by reducing alignment sensitivity, and can be used to make applicable safety standards easier to meet as well.

摘要： A laser measurement system operates to measure portions of a vehicle, such as a vehicle frame. The measurements are used, for example, to determine if the portions of the vehicle are bent or damaged. The measurement system includes a laser scanner and at least one target assembly that can be connected to a point of the vehicle. The laser scanner emits a laser beam that is detected by the target. Time and laser position information detected by the target are used to determine the location of the target, as well as the location of the point of the vehicle. The location of the point is then compared to an original location of the point to determine if damage has occurred.

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： An integrated photonics module includes at least one light source and a MEMS scanner coupled to and held in alignment by an optical frame configured for mounting to a host system. According to some embodiments, the integrated photonics module may include a plurality of light sources and a beam combiner coupled to the optical frame. According to some embodiments, the integrated photonics module includes a selective fold mirror configured to direct at least a portion of emitted light toward the MEMS scanner in a normal direction and pass scanned light through to a field of view. The selective fold mirror may use beam polarization to select beam passing and reflection. The integrated photonics module may include a beam rotator such as a quarter-wave plate to convert the polarization of the emitted light to a different polarization adapted for passage through the fold mirror. The integrated photonics module may include one or more light detectors.
