Abstract
Provided is an optical device including an optics including at least two moving groups that are movable along an optical axis and share portions of driving regions; a plurality of actuators configured to move the at least two moving groups along the optical axis, respectively; and a control unit configured to control the positions of the at least two moving groups by operating the actuators, wherein the control unit moves the at least two moving groups independently, such that the position coordinates of the at least two moving groups in one integrated coordinates system do not coincide with each other.
Claims15
An optical device comprising:
- an optics comprising at least two moving groups that are movable along an optical axis and share portions of driving regions;
- a plurality of actuators configured to move the at least two moving groups along the optical axis, respectively;
- and
- a control unit configured to control the positions of the at least two moving groups by operating the actuators,
- wherein the control unit moves the at least two moving groups independently, such that the position coordinates of the at least two moving groups in one integrated coordinates system do not coincide with each other.
A driving control method for an optical device,
- wherein the optical device comprises:
- an optics comprising at least two moving groups that are movable along an optical axis and share portions of driving regions;
- a plurality of actuators configured to move the at least two moving groups along the optical axis, respectively;
- and
- a control unit configured to control the positions of the at least two moving groups by operating the actuators,
- the driving control method comprising:
- calculating a relationship formula between position coordinates of the at least two moving groups in one integrated coordinates system;
- and
- moving each of the at least two moving groups by using the control unit, such that the position coordinates of the at least two moving groups do not coincide with each other.
