AI Technical Summary
In existing optical systems, the coordination between the central and peripheral regions in multi-zone defocus control is insufficient, resulting in discontinuous defocus distribution, unstable region switching, and difficulty in achieving smooth transition and stable formation of composite defocus structures.
By dividing the field of view into a central optical zone and a peripheral optical zone, a central defocus signal and a dynamic compensation defocus signal are generated. The dynamic compensation defocus signal of the peripheral optical zone is adjusted in real time based on the optical axis deflection and the line of sight movement trajectory, so that it forms a spatial coupling relationship with the central defocus signal, thereby optimizing the continuity of defocus distribution and the stability of regional switching.
It achieves the formation of a continuous and stable composite band of the defocused light field, reduces boundary abrupt changes and defocus breaks during multi-zone switching, and improves the response capability and defocus control accuracy of the optical system.
