PURPOSE:To readily perform the fixing angle adjustement of plane mirrors to a frame by installing a frame for checking and a monitor camera to the focal position and visually recognizing the image of the above-mentioned frame for checking projected on the multiple plane mirrors. CONSTITUTION:A frame 11 for checking of a reflecting mirror 13 is used for the heliostat which tracks solar light 5 and reflects the solar light 5 always in a fixed direction is placed in the focal 7 position of the reflecting mirror 13 and is installed perpendicularly to optical axis 4. With such constitution, one plane mirror 1A is projected on a monitor television 15 and is viewed. If the fixing angle of the plane mirror is correct, the rays 16, 17, 18 emitting from the range A where they oppose to the plane mirror 1A reflect on the plane mirror 1A, reach the focus 7 and are visible as an image B. In this way, whether the fixing angles of the respective plane mirrors of the respective plane mirrors of the reflecting mirror 13 are correct or not may be checked simply by placing the monitor camera 14 at the focus and viewing the monitor television. |
