1. a transverse deformation based on the change of laser exposure rate measures system, it is characterised in that bagInclude sequentially put along horizontal direction laser instrument (1), optical filter (2), condenser lens (3),Photodetector (4) and oscillograph (5), described laser instrument (1), condenser lens (3) and photoelectricityThe geometric center of detector (4) keeps on an axis, and principal plane is the most parallel to each other, described lightElectric explorer and oscillograph (5) electrical connection;

  • Described laser instrument (1) is used for launching laser, and is radiated at by laser and is positioned at laser instrument (1) and poly-On test specimen to be measured (6) between focus lens (3) and test specimen to be measured (6) optical filter behind;

    Described optical filter (2) is used for filtering nature light, retains laser beam;

    Described condenser lens (3) is for by laser focusing;

    The described photodetector (4) laser after collectiong focusing irradiates and perception light intensity signal,The signal of telecommunication that light intensity signal is corresponding is obtained by opto-electronic conversion;

    Described oscillograph (5) is for calculating the signal of telecommunication and showing.
