    Abstract: Laser systems and methods configured to reconstruct an image of an object from an input comprising: the object's scattered intensity distribution (SID) and the object's compact support; the system comprising: a first lens and a second lens, in a four-focal telescope configuration; a gain with a mirror 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 object's SID; a spatial intensity binary mask, located between the telescope's lenses, comprising an aperture in the form of the object's compact support; the mask is configured to transfer only beams passing through the aperture. The reconstructed object's image is provided at least at the mask's aperture.

    Abstract: A method and system for use in reconstruction and retrieval of phase information associated with a two-dimensional diffractive response are presented. The method comprising: providing (75) input data indicative of one or more diffractive patterns corresponding to diffractive responses from one or more objects (50). Dividing (130) said input data into a plurality of one-dimensional slices and determining (140) one-dimensional phase data for at least some of said one-dimensional slices. Tailoring (150) the reconstructed phase data of said one-dimensional slices to form a two-dimensional phase solution. The two-dimensional phase solution is defined by phase shifts of said reconstructed one-dimensional phase data of said one-dimensional slices. The two-dimensional phase solution thus enables obtaining two-dimensional reconstructed phase data suitable for reconstruction of image data (250).

    Abstract: A device (10) for characterization of an optical beam of at least one pulse includes a beam splitter (14) for splitting the optical beam (12) into at least a first beam (12a) and a second beam (12b), and a spectral separator (16) for spectrally separating at least one monochromatic wavelength component of the first beam. The device includes a photosensitive detector (20) for detecting the second beam and one of the monochromatic wavelength components (12c) of the first beam. The device further includes a processor (24) for determining a difference between the time of detection of the pulse of the second beam and the time of detection of the corresponding pulse of the monochromatic wavelength component of the first beam.
