摘要： Apparatus (20) for 3D mapping of an object (28) includes an illumination assembly (30), including a coherent light source (32) and a diffuser (33), which are arranged to project a primary speckle pattern on the object. A single image capture assembly (38) is arranged to capture images of the primary speckle pattern on the object from a single, fixed location and angle relative to the illumination assembly. A processor (24) is coupled to process the images of the primary speckle pattern captured at the single, fixed angle so as to derive a 3D map of the object.

摘要： A mask for enhancing the depth of focus of an optical imaging system is designed by optimizing an optical property (transmittance or reflectance) of the mask relative to the intensity distribution in the system's image plane. Preferably, a desired PSF intensity is selected, a desired misfocus parameter range is selected, and the optical property is adjusted to minimize a measure of the departure of the system's PSF intensity, as computed from the mask's optical property, from the desired PSF intensity, over the entire misfocus parameter range. Most preferably, the desired PSF intensity is selected as the inverse Fourier transform of a desired OTF. Preferably, the mask is fabricated as a DOE.

摘要： An all-optical device for data processing is presented. The device comprises (a) at least one optical waveguide unit made of linear media and configured to provide multiple total internal reflections of light passing therethrough, the waveguide unit comprising a waveguide portion for interaction between reflected light components of input light; (b) an input aperture arrangement formed by at least one input aperture at an input facet of the waveguide portion; and (c) an output aperture arrangement formed by at least one output aperture at an output facet of the waveguide portion. The geometry of the input aperture arrangement and the waveguide portion is selected so as to determine an interference pattern resulting from a diffraction-based interaction between light components of a predetermined wavelength while the light components propagate through the waveguide portion, a location of the at least one output aperture relative to features of the interference pattern being selected to provide at the output an appropriate modulation of at least one parameter of the input light.

摘要： A method and system are presented for imaging an object with image resolution for at least a part of the object exceeding by a predetermined factor a geometrical resolution defined by a detector pixel array. A predetermined aperture coding is applied to the wavefront of a light signal indicative of at least a part of the object to be imaged with the enhanced resolution, while propagating towards the detector pixel array. The aperture coding is predetermined in accordance with aliasing occurring in the detector plane and such as to provide orthogonality of spectral data indicative of a sampled output of the detector, to thereby enable using the aperture code to reconstruct the image of said at least part of the object with the resolution enhanced by said factor.

摘要： An image projecting device and method are presented. The device comprises a light source system, a spatial light modulator (SLM) unit, and an image projection optics accommodated at the output side of the SLM unit. The SLM unit may be reflective or transmissive. The SLM unit comprises an SLM pixel arrangement enclosed between two glass substrates. The pixel array arrangement is formed by a pixel array assembly and at least one microlens assembly. The microlens assembly includes at least one microlens array accommodated proximate of the pixel array assembly. The light source system may comprise n light sources and a light converting means in optical path of light generated by the n light sources, to thereby produce m light beams of different wavelength ranges, wherein m>n. The light source system may comprise a multi-mode laser, thereby reducing a speckle effect in an integrated speckle pattern produced by the multiple modes, as compared to that of a single mode.

摘要： An optical system and method are presented to produce a desired illuminating light pattern. The system comprises a light source (202) system configured and operable to produce structured light in the form of a plurality of spatially separated light beams; and a beam shaping arrangement (210). The beam shaping arrangement is configured as a diffractive optical unit configured and operable to carry out at least one of the following: (i) combining an array of the spatially separated light beams into a single light beam thereby significantly increasing intensity of the illuminating light; (ii) affecting intensity profile of the light beam to provide the illuminating light of a substantially rectangular uniform intensity profile.
