Test targets (also called test charts, test samples or resolution test patterns) are used to determine the efficiency of optical systems. They are used to determine resolution, MTF, depth of field, distortion and telecentricity.
It is necessary to test and calibrate every single system for comparative measurements, especially when dealing with several measuring systems of the same type.
Resolution pattern 1963A is used in compliance with the National Bureau of Standards (NBS standard 1010A) for this resolution test target.
It is composed of 49 test patterns with five vertical and five horizontal lines each (black lines against transparent background).
The distance of the lines tapers from 1 to 250 line pairs per mm. The lines are twelve times longer than their thickness.
