    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.

    Abstract: Provided are an efficient energy-saving return cylinder of a hydraulic press and a working method thereof. The efficient energy-saving return cylinder of a hydraulic press comprises a plurality of single-rod return hydraulic cylinders symmetrically distributed at two sides of a main hydraulic cylinder of the hydraulic press, the plurality of single-rod return hydraulic cylinders are divided into several groups, each of the groups consisting of one balancing cylinder and one driving cylinder; a rod chamber of the balancing cylinder is communicated with an accumulator, the pressurized oil in the accumulator is filled into an oil chamber of the balancing cylinder, so that the balancing cylinder balances the weight of a walking beam and a working part of the walking beam; the driving cylinder is differentially connected; in the process of neutral-stroke-rapid-descending and ascending-returning of the walking beam and the working part of the walking beam.
