Point Spread-Function, Line Spread - Function, and Modulation Transfer Function. Tools for the Study of Imaging Systems! KURT ROSSMANN, Ph.D. Fig. 1.
For a linear imaging system, the line spread function is simply the integral of function and subsequently evaluate the modulation transfer function from the line.
The Modulation Transfer Function, or MTF, is a property of an imaging system that The Modulation Transfer function, MTF (w), is the line spread function. Sometimes it is more practical to define the transfer functions based on a binary black-white stripe pattern. Another factor in digital cameras and camcorders is lens resolution.

The line spread function of the EMI-Scanner was measured and the MTF of the scanner was calculated. The optical transfer function is in this case calculated as the two-dimensional discrete Fourier transform of the image and divided by that of the extended object. In fact, the problem of calculating the PSF from a number of LSF.

Definitions of resolution, even for perfect imaging systems, vary widely. The complex-valued optical transfer function can be seen as a combination of these two real-valued functions: and. Although one typically thinks of an image as planar, or two-dimensional, the imaging system will produce a three-dimensional intensity distribution in image space that in principle can be measured. SA-CME Objectives and Disclosures. The following figures shows the two-dimensional equivalent of the ideal and the imperfect system discussed earlier, next to an optical system with coma , a non-rotational-symmetric aberration. line spread function to mtf

Although the measurement images obtained with this technique illuminate a large area of the camera, this mainly benefits the accuracy at low spatial frequencies. Unfortunately, this method has two significant drawbacks. The usage of these algorithms to the analyzing image largely misrepresents the results for measurement of resolution. The quantity of discernable lines you can shoot tells you the resolution. This is because of the optics, which is often a bottleneck in the modern digital photo technique.
