摘要： A system and method are presented for use in the object reconstruction. The system comprises an illuminating unit, and an imaging unit (see FIG. 1). The illuminating unit comprises a coherent light source and a generator of a random speckle pattern accommodated in the optical path of illuminating light propagating from the light source towards an object, thereby projecting onto the object a coherent random speckle pattern. The imaging unit is configured for detecting a light response of an illuminated region and generating image data. The image data is indicative of the object with the projected speckles pattern and thus indicative of a shift of the pattern in the image of the object relative to a reference image of said pattern. This enables real-time reconstruction of a three-dimensional map of the object.

摘要： Apparatus for projecting a pattern includes a first diffractive optical element (DOE) configured to diffract an input beam so as to generate a first diffraction pattern on a first region of a surface, the first diffraction pattern including a zero order beam. A second DOE is configured to diffract the zero order beam so as to generate a second diffraction pattern on a second region of the surface such that the first and the second regions together at least partially cover the surface.

摘要： A method for three-dimensional mapping of an object, including projecting with a projector a set of fringes on the object and capturing an image of the object in a camera. The method further includes processing the captured image so as to detect a Moiré pattern associated with the object and so as to extract depth information from the Moiré pattern, and configuring the projector and the camera so that a locally unambiguous characteristic of the Moiré pattern is related to a depth of the object.

摘要： A plurality of bits is transmitted by partitioning the bits among n subsets; encoding each subset as a respective symbol; selecting a balancing vector, in accordance with the symbols, from a set of size 2p of codewords of length n in {−1,1}; multiplying each symbol by a corresponding element of the balancing vector; and transmitting the symbols substantially simultaneously. Preferably, the set of codewords has a strength of at most about 2 ln └i┘. The balancing vector is selected either deterministically or probabilistically.

摘要： Optical apparatus includes an image sensor and an optical assembly, which is configured to focus optical radiation via an aperture stop onto the image sensor. The optical assembly includes a plurality of optical surfaces, consisting of a first, curved surface through which the optical radiation enters the assembly, a final surface through which the rays exit the assembly toward the image sensor, and at least two intermediate surfaces between the first and final surfaces. An interference filter, which has a center wavelength and a passband no greater than 4% of the center wavelength, and includes a coating formed on one of the optical surfaces. All rays of the optical radiation passing through the aperture stop are incident on the coating over a range of incidence angles with a half-width that is no greater than three fourths of the numerical aperture of the optical assembly.

摘要： A method for depth mapping includes illuminating an object with a time-coded pattern and capturing images of the time-coded pattern on the object using a matrix of detector elements. The time-coded pattern in the captured images is decoded using processing circuitry embedded in each of the detector elements so as to generate respective digital shift values, which are converted into depth coordinates.

摘要： A method for mapping includes projecting a pattern onto an object (28) via an astigmatic optical element (38) having different, respective focal lengths in different meridional planes (54, 56) of the element. An image of the pattern on the object is captured and processed so as to derive a three-dimensional (3D) map of the object responsively to the different focal lengths.
