PURPOSE:To eliminate a complicated unstable element and to treat an image by providing a simultaneous stereoscopic eyeground camera with an optoelectronic photographic element and a light guiding optical system for guiding a pair of two left and right light fluxes to make them close each other and to a photographic face of an optoelectronic photographic element. CONSTITUTION:An image of eyegrounds is one focused in the neighborhood of a polarized prism 23 by means of a focusing lens 21 and the distance between light axes of left and right light fluxes relayed to an optical system after a light flux separating prism 17 is displaced in the direction for narrowing the distance by a matching prism 22 with two reflecting faces. The image of the eyegrounds is formed on an optoelectronic photographic elements 25 in such a way that the left and the right light fluxes are close to each other by the polarized prism 23 and the second image focusing lens 24. As the optoelectronic photographic element 25 of a TV camera 26, such a photographic element as CCD is used. An optical system before the polarized prism 23 is commonly used with the optical system for photographing and the image of the eyegrounds focused in the neighborhood of the polarized prism 23 is contracted and focused on the optoelectronic photographic element 25. |
