本文概述了用全息位相光栅干涉法将原眼科用的裂缝灯稍做改进便能测定人眼视觉锐度的新技术。
A method of measuring visual acuity with holographic grating is described. The measurement may be performed with a slightly modified conventional ophthalmoscope.
以三角形靶标的视觉锐度为基准，设计了无缝三角形网格划分算法，对典型识别概率的实测红外目标图像进行了等效三角形划分，确定了目标对应的等效三角形数目；
The infrared target in the real background were closely meshed into many equivalent triangle patterns by considering visual acuity, and the number of triangle pattern was statistically determined.
