Summary

We developed a simple method to measure a lens's modulation transfer function (MTF) using computer-generated targets. This technique accurately determines the entire MTF curve in a single measurement, validating theoretical calculations.

Area of Science:

Optical engineering
Image quality assessment

Background:

Accurate lens characterization is crucial for optical system performance.
Traditional modulation transfer function (MTF) measurement methods can be complex and time-consuming.

Purpose of the Study:

To present a simplified and efficient method for measuring the complete modulation transfer function (MTF) curve of a lens.
To validate this method against theoretical calculations.

Main Methods:

Utilized a random test target displayed on a computer screen for MTF measurement in the visible region.
Employed masks to obscure the lens, enabling comparison with theoretical MTF calculations.
Reduced measurement noise by averaging data from a large number of generated targets.
