人眼波前像差主客观测量的信息融合方法

Information fusion method for objective and subjective measurement of wavefront aberrations of human eye

人眼是一个不完善的屈光系统,存在着各种像差,而且视觉不仅与人眼的屈光系统有关,还与主观的判断和神经系统的处理有密切关系.只有主观测量与客观测量相结合,才能得到最佳的视力矫正数据.本文提出了通过信息融合技术把像差的主观测量和客观测量的结果进行融合处理,给出矫正时所需的唯一数据,并通过实验得到了信息融合后的人眼波前像差.

The human eye is not a perfect refractive system, there exists various aberrations in it, and the vision is not influenced only by the refractive system, but also by the subjective judgment and nervous system. The measurement combined of the subjective and objective can give the best correction data. Thus, it is presented that the information fusion method for combination of objective and subjective measurement of human eye to obtain the only correction data which are used for eyes rectification. The experiment gives the ocular＇ s aberrations after the information fusion of the measurement.
