Abstract
A zooming control device includes a filter assembly, a metalens device spaced apart from the filter assembly, and a polarization selection device between the filter assembly and the metalens device. The filter assembly is configured to select a wavelength of light exiting the filter assembly and includes an optical device having an adjustable refractive index that varies with an electric current applied to the optical device. The polarization selection device is configured to select a polarization state of the light exiting the filter assembly and passing through the polarization selection device.
Claims20
A zooming control device comprising:
- a filter assembly configured to select a wavelength of light exiting the filter assembly, the filter assembly including an optical device having an adjustable refractive index that varies with an electric current applied to the optical device;
- a metalens device spaced apart from the filter assembly;
- and
- a polarization selection device between the filter assembly and the metalens device, the polarization selection device being configured to select a polarization state of the light exiting the filter assembly and passing through the polarization selection device.
An optical system comprising:
- a zooming control device including:
- a filter assembly configured to select a wavelength of light exiting the filter assembly, the filter assembly including an optical device having an adjustable refractive index that varies with an electric current applied to the optical device;
- a metalens device spaced apart from the filter assembly;
- and
- a polarization selection device between the filter assembly and the metalens device, the polarization selection device being configured to select a polarization state of the light exiting the filter assembly and passing through the polarization selection device.
The optical system 14, wherein the zooming control device further includes at least one of:
- a first driver coupled to the first mirror and configured to drive the first mirror to move toward or away from the optical device;
- or
- a second driver coupled to the second mirror and configured to drive the second mirror to move toward or away from the optical device.
