Optiskt system och metod för sammanställning av färgbilder från kromatiskt okompenserad optik

摘要

An automatic focus controller (98) determines optical image corresponding to optimal focus of objective (72) for each frequency band, separately. A registration controller (104) aligns the determined optimal images. An objective (72) modifies the electromagnetic radiation received from an object and emits the modified electromagnetic radiation. A camera (32) detects separate images for each frequency band of modified electromagnetic radiation of image emitted by objective. An Independent claim is also included for optical system operating method.
