Abstract

Error correction of optical complex surfaces in computer-controlled optical surfacing (CCOS) is primary important. This paper discusses some methods, i.e. Fourier transform method, Wiener filtering method, directive method and iterative method, for calculating dwell time or relative pressure in the CCOS for error-correcting, which are enlightened from the digital image processing techniques. However, these error correction methods are different from the image processing because they are not a subject of solving the causal signal but a problem of an iterative process. The simulation results show that the Wiener filtering method is good and reliable when the correlative parameters in the fabrication are kept consistent.
