WebSep 1, 2024 · Introduction. To study the image quality a method based on the transfer function is commonly used. In a first step, one function is defined for coherent illumination, that is the Amplitude Transfer Function (ATF), and other is defined for incoherent illumination, that is the Optical Transfer Function (OTF) [1]. WebFor example, in quantum mechanics, there is a consideration for the probability field, which is related to the wave function. The applications of coherent waves can be seen among the future technologies of field quantum computing, etc. Modal analysis: Coherence signal is used in modal analysis to assess the quality of transfer functions.
