Zusammenfassung:The present invention relates to an image information measurement system for obtaining shape images of a target in a high-radiation environment. The image information measurement system includes: a signal transceiver unit which transmits ultra-short pulse signals to the target and receives the ultra-short pulse signals reflected by the target; an image obtaining unit which obtains images of the target by processing the signals received from the signal transceiver unit; an image control processing unit which controls the exposure time of the image obtaining unit to obtain the shape of the target and uses the received image information to store and estimate the shape of the target; a shielding unit including a first space for shielding the radiation irradiated from the target and a second space exposed to the radiation; and radiation-resistant optical fibers which connect the image obtaining unit, image control processing unit, signal transceiver unit arranged in the second space, and signal generating unit arranged in the first space, respectively, while transmitting the short pulse signals. 고 방사능 환경에서 대상체의 형상 영상을 획득하기 위한 본 발명인 영상정보계측시스템은, 극초단 펄스 신호를 대상체에 전송하고, 대상체로부터 반사되는 극초단 펄스 신호를 수신하는 신호송수신부, 신호송수신부로부터 수신한 신호를 처리하여 대상체의 영상을 획득하는 영상획득부, 대상체의 형상을 획득을 위해 상기 영상획득부의 노출 시간을 제어하고, 수신한 영상정보를 이용하여 대상체의 형상을 저장 및 추정하는 영상제어처리부, 대상체로부터 방출된 방사선이 차폐되는 제1 공간과 상기 방사선에 노출되는 제2 공간을 형성하는 차폐부, 제1 공간에 배치된 신호생성부, 영상획득부 및 영상제어처리부와 제2 공간에 배치된 신호송수신부를 각각 연결하고, 단 펄스 신호를 전달하는 내방사선 광섬유를 포함한다.
