Optical transfer function - Wikipedia
WEBThe optical transfer function (OTF) of an optical system such as a camera, microscope, human eye, or projector specifies how different spatial frequencies are captured or transmitted.
WEBThe Optical Transfer Function (OTF) is a complex-valued function describing the response of an imaging system as a function of spatial frequency. Modulation Transfer Function (MTF) = magnitude of the complex OTF.

WEBOverview. Your optic nerve carries visual information from your retina to your brain. What is the optic nerve? The optic nerve is comprised of millions of nerve fibers that send visual messages to your brain to help you see. You have an optic nerve at the back of each eye that connects directly to your brain.

WEBT(k) is called the optical transfer function (OTF). The optical transfer function is the Fourier transform of the impulse response. Let us find the Fourier I'(k) of I'(x) i.e., the Fourier transform of the actual image. I'(k) ∝∫-∞ +∞ I'(x')exp(-ikx')dx' =∫-∞ +∞ [∫-∞ +∞ I g (x'')T(x' - x'')dx'']exp(-ikx')dx'.
WEBThe optical properties of solids provide an important tool for studying energy band struc- ture, impurity levels, excitons, localized defects, lattice vibrations, and certain magnetic excitations.
Optical Transfer Function - an overview | ScienceDirect Topics
WEBAn Optical Transfer Function (OTF) is defined as a measure of the ability to transmit spatial information in the spatial frequency domain. It is represented by H (s), where s is the spatial frequency, and is calculated based on the ray positions from a spot diagram.
Interpretation of the optical transfer function: Significance for …
WEBThe optical transfer function (OTF) is widely used to compare the performance of different optical systems. Conventionally, the OTF is normalized to unity for zero spatial frequency, but in some cases it is better to consider the unnormalized OTF, which gives the absolute value of the image signal.
