Abstract
The visualization of distortion was used for the distorted and undistorted interference fringe pattern by a Michelson interferometer. The half image of this symmetric interference fringe was automatically transformed to the continuous phase image by the automated carrier fringe analysis combined with FFT technique and the phase unwrapping method. Finally, the phase image of distortion was created by the calculated MATLAB programme. In the correction of chromatic aberrations in the lens, the circular Fresnel zone plate is designed by the MATAB algorithm programme. The zone plate image with the high resolution of zone plate curvature surface is obtained by increasing the image pixel size (6000by 6000) and by the camera down system. The designed zone plate is fabricated by photography, and the surface of the fabricated zone plate is observed by WYKO interferometric microscope. Furthermore the chromatic aberration of lens combined with the fabricated zone plate is practically examined. This experiment obtained the reduced chromatic aberration.
