Abstract
A system for evaluating the modulation transfer function (MTF) of a device under test is provided. The system includes an image projector configured to provide light in a pattern representing a desired image. The system further includes a lens configured to direct the provided light toward the device under test as a collimated beam. An image analysis component calculates the MTF for the device under test from the at least one image taken at the device under test and the known characteristics of the image projector and the lens.
