Calibration devices, systems, and methods for calibrating a sensor. In one example a calibrator includes a housing, a dual-axis mirror positioning mechanism disposed within the housing, and a single calibration mirror coupled to the dual-axis mirror positioning mechanism and disposed within the housing, the dual-axis mirror positioning mechanism being configured to rotate the calibration mirror about a first axis to move the calibration mirror from a stowed position into a deployed position and, when the calibration mirror is in the deployed position, to rotate the calibration mirror about a second axis into a plurality of calibration positions, the first and second axes being orthogonal.

Optical calibrator, calibration system, and method

Various embodiments provide a system for moving optical elements. The system includes a first rotor and a second rotor configured to rotate in opposite directions. The system further includes a first plurality of paddles coupled to the first rotor, each of the plurality of paddles having an aperture configured to receive a first optical element, and a second plurality of paddles coupled to the second rotor, each of the plurality of paddles having an aperture configured to receive a second optical element. The first rotor and the second rotor are configured to move the first optical element between a retracted position and a desired position and to move the second optical element between the desired position and a retracted position substantially simultaneously such that a reaction torque of the first rotor cancels a reaction torque of the second rotor.
