Abstract:
PURPOSE: A zoom lens optical system of middle infrared ray wavelength band is provided to be continuously changed over a wide scaling ratio of 1 to 20 times without changing its optical performance in focusing and zooming, remove aberration though consisting of a few of lenses, and easily realizing the mechanical/optical operation and fabrication required to the change of the scaling ratio. CONSTITUTION: The zoom lens optical system of middle infrared ray wavelength band comprises a zooming part and an imaging part. The zooming part changes the scaling ratio of the zoom optical system and consists of 4 lens groups(G1-G4) sequentially disposed from an object. The imaging part reimages a primary imaged middle image and consists of two fixed lenses(6,7) having a positive refraction performance.
Abstract:
The system is for projecting real time images on the monitor by scanning an object with far infrared ray. The system comprises: a vibrating plane mirror(1) vibrating on 60Hz field rate of a standard monitor; a connected mirror(3) for handling the horizontal and the vertical scanning mechanism; a polygon(4) for horizontal scanning; an image displayer(5) for showing the image; and detectors(6) for real time scanning of an object.

본 발명은 평면경인 수직 주사경과, 상기 수직 주사경의 수직 주사를 모아 다시 반사하는 수평 및 수직 주사 메카니즘의 가공이 용이한 연결 거울과, 상기 연결 거울에 의한 주사를 방사하는 회전 다면경인 수평 주사경과, 영상을 맺게하는 결상 렌즈 및 검출기로 구성된 실시간 영상 획득을 위한 2차원 주사 광학계이다. 수평 동기 신호 획득은 수평 주사경의 회전수 및 검출기 수를 조합함으로써 수직 주사경의 특별한 구동 메카니즘 없이 비월주사가 가능하며, 나르시서스 신호를 이용하여 정확하게 수평 동기 신호를 획득하는 방볍에 의해 달성된다.
Abstract:
PURPOSE: An infrared thermal image apparatus including 2D arrangement detection part is provided to reproduce an image without horizontal/vertical scanning, thereby reducing system size and power consumption. CONSTITUTION: An infrared thermal image apparatus including 2D arrangement detection part includes an infrared optical part(100), a reflecting mirror(102), a precision scanning part(104), a detecting part(106), and an image signal processing part(120). The infrared optical part detects an object and generates infrared signal. The reflecting mirror deflects the infrared inputted from the infrared optical part. The precision scanning part precisely scans the infrared deflected and inputted by the reflecting mirror. The detecting part detects the infrared signal with an electrical analog signal corresponding to the size of the each infrared signal. The image signal processing part processes the electrical analog signal detected by the detecting part with an image signal.
