摘要
The folded optical structure used in 4f-based planar-integrated opto-electronic hybrid correlator system, increases aberration and reduces the system's recognition ability. The phase modulation function of micro-optical lens is determined, by using the theory of oblique incidence corrdinates to analyse planar integrated optical correlator structure. Then the system aberration is reduced and thereby the recognition ability is enhanced, by analysing the phase function of micro-optical lens elements and using Zemax software optimization system. The optimized system's maximum optical path difference is less than λ/4 and the system attains diffraction limited performance. The contrastive and quantitating analysis is simulated by Matlab, the result show that the optimized system's recognition performance has been improved by 0.8 times. It shows that the aberration has been improved well, the system's recognition ability has been significantly enhanced.
