Title:
STEREO OPTICAL SYSTEM AND IMAGING APPARATUS
Document Type and Number:
Japanese Patent JP2023104465
Kind Code:
A
Abstract:
To maximize an image circle formed on one imaging element by two optical systems arranged in parallel.SOLUTION: A stereo optical system forms image circles 103 and 105 on one imaging element IP by two optical systems 101 and 102 arranged in parallel. Each of the optical systems has an angle of view in which other optical system is reflected in first regions 104 and 106 outside in a parallel arrangement direction in the image circles, and a field stop RC so as to lower a light amount of second regions 107 and 108 inside in the image circles. A distance between optical axes of the two optical systems and image circle diameters are set so that a distance between centers of the image circles on the imaging element is shorter than the image circle diameters, third regions 103a and 105a between the first regions and the second regions in the image circles are brought into close contact with each other or adjacent to each other, and the first region is out of the imaging element.SELECTED DRAWING: Figure 17
