title: Computer assisted optical surfacing.
abstract: Computer Assisted Optical Surfacing (CAOS) is a modern system for optical fabrication. A computer is used to calculate the effects of moving a lap on an optical surface. A mathematical deconvolution technique is used to specify lap motions to correct a surface error. Application of the CAOS system operation of an XY machine in the fabrication of off-axis segments of general aspherics is described.
