Image analysis system

摘要

A system for quickly measuring and displaying in real-time a variety of performance characteristics of optical components such as lenses. The system is video based and is under the control of a computer which uses a windowing software program to provide the user with a graphical user interface by which the various components of the system and test lenses may be characterized and operated on through functions available via the interface. Lens performance measurements such as line spread and modulation transfer functions can be graphically and numerically displayed in real-time and/or recorded on other output devices or as files in computer memory.
