利用光学中调制传递函数(MTF)的概念,来研究人的视觉信息加工特性,已经取得相当成绩,受到视觉生理学界的重视,在眼科临床上也得到了应用。近年来国内、外的许多研究报道表明,用光学调制传递函数(眼科临床上常称为对比敏感度函数CSF)对视觉异常非常敏感,是发现,监视和诊断视觉异常的一种非常灵敏和有效的手段。并且由于它所包含的信息比起眼科中传统的视敏度(仅相当于MTF曲线中截止频率)来要
The use of the concept of modulation transfer function (MTF) in optics to study the processing characteristics of human visual information has achieved considerable success and is valued by the visual physiology community and has also been applied clinically in ophthalmology. In recent years, many studies at home and abroad have shown that the use of optical modulation transfer function (ophthalmology clinically often referred to as the contrast sensitivity function CSF) is very sensitive to visual abnormalities, is to detect, monitor and diagnose visual abnormalities is a very sensitive and effective s method. And because it contains more information than the traditional visual acuity in ophthalmology (which corresponds only to the cutoff frequency in the MTF curve)
