HIGH-MAGNIFICATION CONTINUOUS ZOOM FAR-INFRARED OPTICAL SYSTEM

摘要

The present invention relates to a high-magnification continuous zoom far-infrared optical system. The optical system has a structure having an object lens facing an object to capture a phase by receiving far-infrared rays of the object and a magnification lens, a fixed lens, a compensation lens, and an imaging lens successively arranged from a rear side of the objective lens in an optical axis direction. The magnification lens converts a magnification of the phase while moving in the optical axis direction. The compensation lens compensates a defocus occurred in the distance and temperature variation of the object while moving in the optical axis direction. The imaging lens forms the phase which the object lens receives and has a far-infrared uncooling detector converting the phase formed by the imaging lens to the digital image signal, and then outputs the digital image signal.;COPYRIGHT KIPO 2016
