Product Description

产品描述

·Limiting resolution can be measured by calculating linear distance from center of chart along a radius to the point at which detail has lost enough contrast to be no longer visible.

极限分辨率可以通过测量沿半径方向已经失去了足够的对比度无法看清的点到中心的距离换算得出。

Warning: This chart has been designed to be very hard for any camera to reproduce accurately.（）


警告:这个测试卡很暴力，不是所有的相机都能拍摄并解析。
