Design and Realization of Focus Auto Adjustment for Imaging CCD in Retinal Aberration Correction Setup
A focus auto adjusting system for the LCOS retinal aberration correction setup was built to locate the best position of CCD imaging plane. It resolved the problem that CCD was usually not in the best imaging plane. The system adopted Step-Calculation-Comparison method. Through comparing the correlation and blurring level of two neighbor images
it can find the best imaging position within short time. Using the system
doctors can obtain more valuable retinal images through adaptive optics system than traditional fundus system. In addition
it can also realize several small view angle retinal images stitching
and monitor large view angle retinal area in real time.
