Line widths per picture height
NettetThis target is designed to test resolution of electronic still picture cameras, and complies with ISO 12233. ... Features on the chart range from 100 to 2000 LW/PH (line widths per picture height), which corresponds to the finest feature being 0.1mm. This test chart is offered in three sizes to accommodate a variety of cameras and lenses. NettetThe chart shows line widths per picture height (LW/PH) which can be taken as a measure of sharpness.

The image below is a sine wave— a pattern of pure tones— that varies from low to high spatial frequencies. The top portion is the original sine pattern.
