| Abstract: | A reflective projection system based on Zernike polynomial surfaces is presented.The reflective projection system consists of three reflective mirrors with Zernike polynomial surfaces.The first mirror is concave to reduce the size of the second mirror and obtain high contrast ratio.The second mirror and the third mirror are convex to achieve a shorter projection distance and correct major aberration such as spherical aberration,coma aberration and distortion.The system is simulated and analyzed in detail by using ZEMAX software.Experimental results show that under the condition of relative aperture F-number=2.8,the MTF is more than 50% at 60lp/mm,the maximum distortion is less than 3.0% at screen amplification factor of 80,the designed system can satisfy the requirement of the high definition projection display. |
