Advanced Smart High Ratio Zoom System with Global Optimization

Abstract

With an aim to achieve a breakthrough the choke point in research on system design, to achieve the transforming in multiple fields of view, the approaching to system efficacy limit in theory and improving smartness, pure diffractive optical system is chosen. The top idea and main strategy is developed. Some correlative model is established. In optimized design, global optimization algorithm is used to achieve wider spectrum range, multi field view, lower distortion and appropriate MTF. A kind of result works mainly in 3~5%m and 8~12%m with high ratio of more than 20:1 is evaluated. And this integrated multi-sensor electro-optical system satisfies the applied requirements o some criteria, such as Modulation Transfer Function (MTF), Spot Diagram (RMS) and Point Spread Function (PSF) etc., and achieves remarkable advantages in volume, weight, system efficiency and so on.
