In1943, Carl Zeiss also developed a procedure to measure lens imagequality with so-called “MTF” curves (modulation transfer function), which numerous manufacturers today use for quality control.

1943年卡尔蔡司同样研发了一套利用MTF（调制传递函数）

In this paper the MTF system, using a new counting method and CMOS sensor as device for image reception, is discussed in detail.

本文详细讨论了一种采用全新计算方法，并以CMOS为图像接收器件的调制传递函数测量系统。

The modulation transfer function(MTF) is one of the fundamental parameters to evaluate the infrared optical lens.

调制传递函数是评价红外光学镜头性能的最基本的技术指标之一。
