Abstract: Laser systems and methods configured to reconstruct an image of an object from an input comprising: the objects scattered intensity distribution (SID) and the objects compact support; the system comprising: a first lens and a second lens, in a four-focal telescope configuration; a gain with a minor at one end, at first end of the telescope, configured to amplify and reflect a received beam; a reflective spatial light modulator, at second end of the telescope, configured to selectively reflect intensity distributions of a received beam, according to their spatial location, the selective reflection is configured to maintain the intensity distributions of the objects SID; a spatial intensity binary mask, located between the telescope's lenses, comprising an aperture in the form of the objects compact support; the mask is configured to transfer only beams passing through the aperture. The reconstructed objects image is provided at least at the mask's aperture.
