hear lens is sinilar to the double frequency grating used in i ahearing-interferonetry. In perforning the inage subtraction, the shear lens is tilted at a ' suitable angle such that the light path traveled by the two input inages is differ^ by '"'/I and so that the subtraction between the inage can… … RECOROINO FLATE Figure 6.
