Notes:
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 relativepressure in the CCOS for error-correcting, which are enlightened from the digital image processingtechniques. However, these error correction methods are different from the image processing becausethey are not a subject of solving the causal signal but a problem of an iterative process. The simulationresults show that the Wiener filtering method is good and reliable when the correlative parameters inthe fabrication are kept consistent
