Abstract
An imaging unit includes an imaging element, an imaging optical system that includes an off-axis parabolic mirror, and a driving mechanism. A reflective surface of the off-axis parabolic mirror is configured to face an object. The driving mechanism is configured to change positions of the imaging element and a part of the imaging optical system so as to change an imaging direction of the imaging unit while maintaining a position of a focal point of the off-axis parabolic mirror.
Claims7
An imaging device configured to capture an image of an object, the imaging device comprising:
- an imaging element;
- an imaging optical system;
- and
- a driving mechanism configured to change positions of the imaging element and a part of the imaging optical system, wherein
- the imaging optical system includes an off-axis parabolic mirror, and
- the driving mechanism is configured to change the positions of the imaging element and the part of the imaging optical system so as to change an imaging direction of the imaging device while maintaining a position of a focal point of the off-axis parabolic mirror.
A distance measuring device configured to measure a distance to an object, the distance measuring device comprising:
- a first imaging unit and a second imaging unit arranged such that optical axes of the first imaging unit and the second imaging unit intersect with each other at a convergence angle;
- and
- an image processor configured to calculate a distance to the object based on plural images of the object captured by the first imaging unit and the second imaging unit, wherein
- each of the first imaging unit and the second imaging unit includes:
- an imaging element:
- an imaging optical system;
- and
- a driving mechanism configured to change positions of the imaging element and a part of the imaging optical system,
- the imaging optical system includes an off-axis parabolic mirror, and
- the driving mechanism is configured to change the positions of the imaging element and the part of the imaging optical system so as to change an imaging direction of the each of the first imaging unit and the second imaging unit while maintaining a position of a focal point of the off-axis parabolic mirror.
