PLURAL VISUAL FIELD PHOTOGRAPHING OPTICAL PATH BENDING UNIT, PLURAL VISUAL FIELD PHOTOGRAPHING DEVICE, THREE-VISUAL-FILED PHOTOGRAPHING OPTICAL PATH BENDING UNIT, AND THREE-VISUAL-FIELD PHOTOGRAPHING DEVICE

摘要

The invention relates to an optical path bending unit used for photographing a plurality of visual fields by a single camera, and it also relates to a plural visual field photographing device using the same. A plural visual filed photographing device (1A) according to the invention is composed of an optical path bending unit (11) and a camera (2). The optical path bending unit (11) is a device for allowing the light from the right and left visual fields to be incident on the camera (2), and is composed of a left-hand visual field prism (12) and a right-hand visual field prism (13). The light from the left-hand visual field is incident on the first surface (12a) of the left-hand prism (12). The incident light is totally reflected by a second surface (12b). The totally reflected light is reflected by a third surface (12c). The reflected light is incident on the second surface (12b) and goes outside the left-hand visual field prism (12). The outgoing light from the individual visual fields is incident on the camera (2).
