%X Based on the disadvantages of the MTF for evaluating the imaging quality of CCD cameras,the MRC was presented and the system of measuring MRC was developed,in which two coinciding integrating spheres were proposed to illuminate two sides of the target respectively.The variable contrast could be obtained by regulating the luminance of integrating spheres.Experimental results indicate that the error of measuring luminance is within ±0.3 cd/m2,MRC rises with the increase of the spatial frequency,and the method proposed is a rapid and effective approach to evaluate the imaging quality of CCD cameras.
