Abstract

The research reveals that there are higher-order aberrations in visual optical systems, and the important factors are higher-order aberrations that affect the quality of vision to further improve. To correct the higher-order aberrations, the aberrations of vision system must be effectively measured and analyzed. It is important to use the wave-front aberration technology at the human ophthalmology disease diagnosis, especially in the field such as vision correction. Based on that has been achieved, based on the Hartmann-Shack sensor a wave-front aberration measuring optical system combining of the objective and subjective , the error of the wave-front aberration measurement data has been analyzed, the required parameters in the human eye aberration correction were given, the expression based on information fusion technology were gained. In this paper, the control system of wave-front aberration measurement unit has been in-depth analysis and research. The measurement data acquisition system has been designed ,in the system, the information of lighting optical path, the objective measurement optical path and subjective measurement optical path and other information are fusion. A realistic program for control system design and peripheral interface circuit design has been given.
