Abstract: A double loop optimization apodized lens was designed in this paper. The apodized lens was composed of a concentric alternating arrangement of the transparent ring and annular ring. After bicyclic apodization mirror modulated light is incident to the optical receiver system, the optical imaging system of the received light imaging focuses, data acquisition and processing system for collecting and processing curren signal, isoplanatic angle can be given along the measurement path. Relative to the domestic existing single aperture apodization mirror, the apodized lens is able to simulate the aperture filter function W(z)cz5/3 well at all. The relative error of the resulting isoplanatic angle is significantly smaller. The high-precision measurement of isoplanatic angle can be achieved.
