主　　题：ultrathin metal film dispersion compensation back propagation network LCD-CCD system 

摘      要：A dispersion compensation method is introduced to correct the distorted image passing through an ultrathin metal *** LCD-CCD system is modeled by the back propagation network and used to evaluate the transmittance of the ultrathin metal *** samples for the network come from 729 images captured by shooting test patches,in which the RGB values are uniformity distributed between 0 and *** RGB value of the original image that will be distorted by the dispersion is first transformed by mapping from the LCD to the CCD,multiplied by the inverse matrix of the transmittance matrix,and finally transformed by mapping from the CCD to the LCD,then the corrected image is *** order to verify the effectiveness of the proposed method,ultrathin aluminum films with different thicknesses are evaporated on glass substrates and laid between the CCD and *** results show that the proposed method compensates for the dispersion successfully.
