Description
technical field [0001] The invention belongs to the technical field of optical processing, and relates to a control system and method for an optical processing testing machine, in particular to a control system and method for an optical processing testing machine based on an active support platform, and in particular to a cable-driven optical processing Testing machine control system and method. Background technique [0002] At present, for the polishing of optical mirrors, especially for the polishing of off-axis aspheric mirrors, traditional optical processing techniques such as small grinding heads will introduce copy effects, edge effects, etc. during the processing, and it is difficult to independently complete high-precision, high-steep Polishing of off-axis aspheric mirror surfaces. Ion beam polishing is a processing method with high certainty and good stability, which has higher processing efficiency and reliability, especially in the stage of fine polishing, which ...
