Accordingly, a measurement frequency is freely selected, and the measurement can be carried out in an ideal measurement environment of not being influenced by changes in wind, sunlight and temperature, whereby the mirror surface can be adjusted with high accuracy.

    摘要： Disclosed is an image capturing apparatus comprising a primary mirror 1 that has a surface which is a section of a surface cut out from a paraboloid with a single focus; a secondary mirror 2 that has a surface which is a section of a surface cut out from a hyperboloid with two foci; and a photodetector 3 which converts the light signal coming from the secondary mirror 2 into an electric signal. The secondary mirror 2 is placed in a position where one of its foci and the focus of the primary mirror 1 match with each other. The photodetector 3 is placed near the other focus of the secondary mirror 2. By using two mirrors, the light from the object is led to the photodetector 3 without being shaded.
