AUTOMATIC FOCUSING OPTICAL ASSEMBLY, SYSTEM AND METHOD

摘要

An automatic focusing optical system and assembly including an objective lens subassembly, a sensor electronically connected to a processor, and a dichroic filter for passing light of a first wavelength to the sensor and reflecting light of a second wavelength. A method of auto-focusing including receiving an image of an object comprising a first wavelength and a second wavelength, wherein the first wavelength is passed through a dichroic filter to a sensor and the second wavelength reflected, analyzing the distance of the object based on the first wavelength, generating at least one signal to an objective lens subassembly comprising a drive mechanism arranged to displace an optical lens, and displacing an optical lens along an optical axis to focus the image.
