Assessing image sharpness with MTF.

How to Measure MTF

How to Measure MTF Introduction With the growing role played by optical devices in measurement, communication, and photonics, there is a clear need for characterizing optical components. A basic and useful parameter, especially for imaging systems, is the Modulation Transfer Function, or MTF. Over the past few decades technological advances, including the laser interferometer, high-speed […]
