英文摘要： This project aims to study the dispersion property of sub-wavelength photon sieve by means of theoretical analysis, numerical simulation and experimental　verification. Firstly, we will establish a dispersion model of sub-wavelength photon sieve, find out the influence factors and the influence rules on dispersion property, and propose an approach for dispersion compensation. Then, an experimental system will be set up for testing the dispersion property, a grating phase detection method will be proposed to solve the problems caused by small focal,short depth of focus,difficult testing of the sub-wavelength photon sieve. Finally, the numerical simulation results will be compared with the experimental results for verifying the effectiveness of the proposed physical model, which will be further improved to form a good theoretical and experimental basis for its practical applications in the field of the wide-spectrum imaging,such as bionics,etc.
