Description

technical field [0001] The invention relates to the field of ultra-precise detection of complex curved surfaces, in particular to an in-situ detection device and detection method for free-form surface optical elements. Background technique [0002] The free-form surface optical element is conducive to simplifying the system structure, reducing the number and size of the lens, improving the imaging quality, and obtaining many special optical properties, which brings great potential to the design of new products. Therefore, free-form surface optical components have more and more urgent demands in both military and civilian fields, such as large-scale astronomical observation systems, military photothermal imaging devices, missile guidance systems, digital display systems, automotive lighting systems, ophthalmic medical systems, etc. . At present, there are two main methods for in-situ detection of free-form surface optical components based on ultra-precision lathes: 1. Measur...
