点扩散函数与光学传递函数(Optical Transfer Function, OTF)密切相关,点扩散函数的傅里叶变换即为OTF。光学传递函数是一个关于空间频率的复函数,它的模称为调制传递函数(Modulation Transfer Function, MTF),它的相位称为相位传递函数(Phase Transfer Function, PTF)。一般用MTF进行光学系统的像质评价。PSF在空域表征光...
该方法一般会在物面上固定一块星点板，在星点板后方设置光源，通过星点板遮挡光源，以星点板通光孔...
point spread function的意思是点扩散函数。这是图像处理、光学以及信号处理等领域中的一个重要概念，用于描述一个点源经过一个系统后的扩散情况。该函数能够反映系统的分辨率和成像质量。具体来说：在光学中：点扩散函数描述了光学系统对点光源的成像效果，即一个理想的点光源经过光学系统后，其图像会扩散...

1.2.2 The Point Spread Function The Point Spread Function and Pupil Function The performance of an imaging system can be quantified by calculating its point spread function (PSF). The amplitude PSF, h(x,y), of a lens is defined as the transverse spatial variation of the amplitude of the ...
Instead of working on the collimator''s shape, the problem is addressed by optimizing the point spread function (PSF) with respect to the performance of the reconstruction algorithm in terms of resolution modelling. The optimization is based on an object-dependent cost function that takes into ...
