Paper Abstract

The optical lens quality is traditionally justified by resolution. But the modulation transfer function (MTF) is a better way to measure the optical lens quality than resolution. Before the introduction of linear CCD, it was very difficult to measure the MTF because it was both time consuming and costly. A low cost, high speed MTF measurement by linear CCD has been successfully developed here. Besides the MTF measurement, the important lens characteristics like distortion, optical axis misalignment, relative F number, magnification, and back focus length also can be measured by this system with a very high speed and low cost fully computerized system using a personal computer (PC). This system has been applied in industry and has been proven to be a useful instrument for optical lens characteristics measurement.
