Document Type and Number:
Japanese Patent JP2015197502
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an observation device that has a correction optical system optically correcting an influence on transmission light in accordance with a bobbing direction when a different distortion occurs in accordance with the bobbing direction of a bobbing optical system by an optical wave dome covering the bobbing optical system capable of adjusting an image acquisition direction by a bobbing action.SOLUTION: A correction optical system is provided that corrects transmission light, in which incident light from an outside of an optical wave dome as parallel light passes through and parallelism is lost, to parallel light parallel to a bobbing direction before being incident upon a bobbing optical system. A correction characteristic of the correction optical system is different in accordance with the bobbing direction.
