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-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： In imaging system (100), a spatial light modulator (101) is configured to produce images (102) by scanning a plurality light beams (104,105,106). A first optical element (107) is configured to cause the plurality of light beams to converge along an optical path (114) defined between the first optical element and the spatial light modulator. A second optical element (115) is disposed between the spatial light modulator and an output of the imaging system. The first optical element and the spatial light modulator are arranged such that an image plane (117) is created between the spatial light modulator and the second optical element. The second optical element is configured to collect the diverging light (118) from the image plane and collimate it. The second optical element then delivers the collimated light to a pupil (120) on the other side of the second optical element relative to the spatial light modulator.

摘要： A encoded image projection system (100) is configured to determine the proximity of the system to a projection surface (106). The encoded image projection system (100) includes a light encoder (105) that scans a non-visible light beam (115) on the projection surface (106) selectively when scanning visible light to create an image. A detector (118) is then configured to receive reflections of the non-visible light beam (115) from the projection surface (106). A control circuit (120) is configured to determine the distance (124) between the projection surface (106) and the system from, for example, intensity data or location data received from the detector (118). Where the distances (124) are below a threshold, the control circuit (120) can either reduce the output power of the system or turn the system off.
