MTF Measurement Using Narrow Slit Target and CCD Array   - Details
The modulation transfer function (MTF) is a quantitative image quality metric for imaging systems that takes into account aberrations, diffraction effects and any other process that reduces contrast. It provides a basis for comparison between quality of imaging systems or lenses of similar configurations. This test plan demonstrates a fast means of measuring the MTF of a simple imaging system (a lens singlet) with readily available equipment.

Modulation Transfer Function - what is it and why does it matter?   - Details
Modulation Transfer Function or "MTF" is the most widely used scientific method of describing lens performance. What is it exactly, how is it defined, and how is it measured? The modulation transfer function is, as the name suggests, a measure of the transfer of modulation (or contrast) from the subject to the image. In other words, it measures how faithfully the lens reproduces (or transfers) detail from the object to the image produced by the lens.

MTF - Modulation transfer function   - Details
Modulation transfer function (MTF) is commonly used to describe the outcome of the interaction of two or more PSF. More specifically, the combined intensity distribution resulting from point-image patterns close enough to affect each other. The MTF is a part of a complex function describing this phenomenon, called Optical transfer function, or OTF.
