  • Optical scanning devices and systems
    Patent number: 9285581
    Abstract: Optical scanning devices and systems are disclosed. In one aspect, an optical scanning device comprises a first rotatable optical component and a second rotatable optical component. The first and second optical components are configured to rotate about a common optical axis and further configured to deflect an optical path of light transmitted or received through the optical scanning device. The device further comprises a mounting bracket positioned between the first and second optical components and comprises first and second motor assemblies configured to rotate the corresponding first and second optical components about the optical axis independently of each other. An inner portion of each of the first and second optical components is mounted to an outer portion of the corresponding first and second motor assemblies such that the optical axis is configured to extend through the center of the first and second optical components and tubes.
