SYSTEM AND METHOD FOR AUTOFOCUSING AN OPTICAL SYSTEM THROUGH IMAGE SPECTRAL ANALYSIS
A system and method of autofocusing an optical system uses transforms of images or portions of images formed by the optical system. A detector is used to capture images at different positions relative to the optical system. Transforms and blur spread parameters are calculated for the images for use...

| Zusammenfassung: | A system and method of autofocusing an optical system uses transforms of images or portions of images formed by the optical system. A detector is used to capture images at different positions relative to the optical system. Transforms and blur spread parameters are calculated for the images for use in determining a position to which the detector should be moved to autofocus the system. |
