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 ...
Considering diffraction effect based on scalar theory, we deduced a formula for point spread function of the coded aperture and discussed the ring coded aperture in detail. 基于标量衍射理论,考虑衍射效应的条件下,从理论上推导了编码孔径点扩散函数的公式,并对环形编码孔径进行了详细的讨论。 For infrared...
In calculations of the point spread function, conservation of energy between the pupil plane and image plane should be satisfied. However, the conventional treatment is inadequate especially for quantitative theoretical inference (Shibuya and Ooki, 2005). In this paper, we first derive a formula of...
its far-field PSF is still challenged to be expressed as a mathematic formula. In order to understand the distance-dependent PSF under SELFI, we conducted a numerical simulation by finite element analysis (JCMwave, details in Supplementary Information Note3). We calculated the far-field image pa...

Phil Maffetone’s 180 formula. 180 – your age = your training heart rate or MAF According to Maffetone, you should modify this number: “If you have or are recovering from a major illness (heart disease, any operation or hospital stay, etc.) or are on any regular medication, subtract ...
This is the renowned Rossi-alpha formula without delayed neutrons, which can only be considered as a probability, even approximately, if both intervals dθ and du in (4.149) are infinitesimally small. The derivation of this formula with the inclusion of delayed neutrons is given in Part II, ...
