Abstract
Due to the unique advantages of complex curved aluminum mirrors, its application in optical systems is becoming more and more widespread. However, the accuracy of optical mirrors that are only processed by ultra-precision turning is limited by the error reflection of ultra-precision turning, which can only meet the application requirements of infrared systems, and its further promotion and application have encountered bottlenecks. The combined processing technology of ultra-precision turning, magnetorheological polishing, and computer-controlled surface forming (CCOS), combined with the computational hologram method (CGH) of the complex optical curved surface (CGH) surface shape detection technology, can further improve the surface shape accuracy of the aluminum reflector, to meet the application requirements of visible light systems, and lay the foundation for the promotion and application of complex curved aluminum alloy mirrors.
