Abstract: A system for object reconstruction includes an illuminating unit, comprising a coherent light source and a generator of a non-periodic pattern. A diffractive optical element (DOE) is disposed in an optical path of illuminating light propagating from the illuminating unit toward an object, thereby projecting the non-periodic pattern onto an object. An imaging unit detects a light response of an illuminated region and generating image data indicative of the object within the projected pattern. A processor reconstructs a three-dimensional (3D) map of the object responsively to a shift of the pattern in the image data relative to a reference image of the pattern.

Abstract: 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.
