摘要： Briefly, in accordance with one or more embodiments, an optical relay comprises a partially-reflective-coated Fresnel lens or similar low-profile lens such as a diffractive lens or a holographic lens having a first index of refraction and a filler medium having a second index of refraction and being disposed adjacent to the Fresnel lens. The optical relay enables the optical power of the Fresnel or similar low-profile lens embedded within the two layers to influence a beam that is reflected from the optical relay while allowing transmitted light to experience little or no influence from the embedded lens.

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： 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.
