Method and system for object reconstruction

A system for use in the object reconstruction, the system comprising:

• (a) an illuminating unit comprising a coherent light source and a light diffuser is unit accommodated in the optical path of illuminating light propagating from the light source towards an object thus projecting onto the object a coherent random speckle pattern;
• and an imaging unit for detecting a light response of an illuminated region and generating image data, the imaging unit and the diffuser being oriented so as to provide substantially equal distances from the diffuser and the imaging unit to the object,
• the image data being indicative of the object with the projected species pattern and thus indicative of a shift of the pattern in the image of the object relative to a reference image of said pattern, the system thereby enabling real-time reconstruction of a three-dimensional map of the object.

A projection module for use in a system for object reconstruction, the projection module comprising a coherent light source and a light diffuser configured for that diffusing light impinging thereon by addition of random phase, thereby producing a random speckle pattern for projecting it onto an object thereby enabling imaging of the object with the projected pattern and real time processing image data for reconstructing a three-dimensional map of the object.

A method for use in real-time reconstruction of an object, the method comprising:

• (i) projecting onto the object a random speckle pattern formed by illuminating coherent light;
• (ii) detecting a light response from the object and generating image data of the object with the projected speckles pattern;
• (iii) processing the image data to determine a shift of the pattern in the image of the object relative to a reference image of said pattern, thereby determining a three-dimensional map of the object.
