modulation transfer function frequency的意思|示意

According to optical transfer function, degree of modulation and apperceive degree of space frequency vision vs object image, TIFF grayscale scenograph is made.

根据光学传递函数、调制度和空间频率视觉及对物象的感知程度，制作TIFF格式透视灰度图。

Method Modulation transfer function (MTF) was used to analyze the spatial frequency transfer characteristics of ct and MRI.

调制传输函数可对线性影像系统的频率传输特性进行描述。

The result indicates that the ratio of the detectivities is approximately equal to the modulation transfer function of SPRITE detectors in the region of low spatial frequency, which is near 1.

在低空间频率范围内，后者和前者的探测率比近似等于SPRITE探测器的调制传递函数，接近于1。
