Abstract
카메라의 실상 파인더 시스템은 대물렌즈, 접안렌즈 및 편향 시스템을 가진다.The actual finder system of the camera has an objective lens, an eyepiece and a deflection system.
편향시스템은 대물렌즈와 접안렌즈 사이에 위치한 정립시스템을 포함한다.The deflection system includes a sizing system located between the objective lens and the eyepiece.
파인더 시스템은 또한 대물렌즈의 상평면 위에 놓여진 LCD패널을 포함하며, 이 LCD패널은 접안렌즈를 통하여 관찰되는 정보를 표시한다.The finder system also includes an LCD panel placed on the image plane of the objective lens, which displays the information observed through the eyepiece.
제1편광자가 대물렌즈와 LCD패널 사이에 위치되는 반면 제2편광자는 LCD패널과 접안렌즈 사이에 위치된다. 제1 및 제2편광자는 그들의 투과축이 서로 수직하도록 배열된다. 더우기 편향시스템의 적어도 하나의 광학부재가 제1편광자 및 제2편광자 사이에 놓여진다.The first polarizer is located between the objective lens and the LCD panel while the second polarizer is located between the LCD panel and the eyepiece. The first and second polarizers are arranged such that their transmission axes are perpendicular to each other. Furthermore, at least one optical member of the deflection system is placed between the first polarizer and the second polarizer.
