Abstract
A deformable mirror unit 7A including a plurality of segment mirrors 71 each having a surface 71a, a flexible member 72 configured to connect the plurality of segment mirrors 71 to each other, a driver 74 configured to apply a driving force to at least one of the segment mirror 71 and the flexible member 72 so as to change at least one of a position and a tilt of the reflection surface 71a of each of the plurality of segment mirrors 71, and a connector 73 configured to connect the driver 74 to at least one of the segment mirror 71 and the flexible member 72 and to be rotatable so as to change a light reflecting direction by the at least one reflection surface 71a is provided.
Claims30
A mirror unit comprising:
- a plurality of reflectors, each having a reflection surface;
- a flexible member configured to connect the plurality of reflectors to each other;
- a driver configured to apply a driving force to at least one of the reflector and the flexible member so as to change at least one of a position and a tilt of the reflection surface of each of the plurality of reflectors;
- and
- a connector configured to connect the driver to at least one of the reflector and the flexible member, the connector being rotatable so as to change a light reflecting direction by the at least one reflection surface.
An image acquisition unit comprising:
- an imaging optical system configured to form an optical image of an object;
- an image sensor configured to photoelectrically convert the optical image of the object formed by the imaging optical system;
- and
- a mirror unit, arranged on an optical path between the imaging optical system and the image sensor, and configured to reflect light from the imaging optical system to the image sensor,
- wherein the mirror unit includes:
- a plurality of reflectors, each having a reflection surface;
- a flexible member configured to connect the plurality of reflectors to each other;
- a driver configured to apply a driving force to at least one of the reflector and the flexible member so as to change at least one of a position and a tilt of the reflection surface of each of the plurality of reflectors;
- and
- a connector configured to connect the driver to at least one of the reflector and the flexible member, the connector being rotatable so as to change a light reflecting direction by the at least one reflection surface.
An optical system comprising:
- an imaging optical system configured to form an optical image of an object;
- and
- a mirror unit configured to reflect light from the image optical system to the image sensor
- wherein the mirror unit includes:
- a plurality of reflectors, each having a reflection surface;
- a flexible member configured to connect the plurality of reflectors to each other;
- a driver configured to apply a driving force to at least one of the reflector and the flexible member so as to change at least one of a position and a tilt of the reflection surface of each of the plurality of reflectors;
- and
- a connector configured to connect the driver to at least one of the reflector and the flexible member, the connector being rotatable so as to change a light reflecting direction by the at least one reflection surface.
