人眼是一种有趣的复杂构造和相对简单构造的混合物。我们来看一下它是如何跟踪活动目标的。人眼连续扫描环境并捕捉感兴趣的目标以便细致地观察。这种行为是因视网膜周边区的空间分辨率低、凹斑或者中心区的分辨率高而造成的。美国费城宾夕法尼亚大学的有关专家认为,人眼感光体的这种排列方式减少了视网膜中的感光体的数量,减小了视神经甚至视脑的尺寸,但仍可进行高分辨率成像。 The human eye is a mixture of interesting and complex constructions and relatively simple constructions. Let’s take a look at how it tracks the activity. The human eye continuously scans the environment and captures the object of interest for careful observation. This behavior is caused by the low spatial resolution of the peri-retinal area and the high resolution of the concave or central area. Experts from the University of Pennsylvania in Philadelphia believe that this arrangement of human photoreceptors reduces the number of photoreceptors in the retina and reduces the size of the optic nerve and even the brain, yet enables high-resolution imaging.
