Optical device serving to be explored field - images of large size

摘要

P the present invention relates to an optical device serving to be explored field - images of large size. / p & & p & it is an object of the input 1 downstream of which, in the direction of the incident rays, it has made a return mirror 2 and 3 in the form of a prism edge of the roof. A polygon 4 of refraction is mounted rotating around an axis 5 to the - the top of the base surface of the prism. It has made a return mirror 6 and an outer lens 7 containing in its plane of a sensor 8. In order to write the length of the lines of the image, it is used for the prism 3 in the form of a roof aret move back and forth at right angles to its edge and the rotating prism 4 writes the small angle of the image, that is - to - say the height of the latter. / p & & p & the invention applies to the scanning and reproduction of fields - images of large size. / p
