A method which expands the compressed images due to Ritchey Angle and rotates the plane under test is presented  achieve two sets of influence functions through this we can built two equations according to two different angular positions  we can solve the equations by least squares method. Then through fitting the coefficients  we can get the flat errors  this paper describe the simulation test of the method in order to prove the feasibility and reliability of this method.
