Abstract
The techniques of this disclosure relate to a system for adjusting a focus of an image. A system includes a phased metalens configured to adjust a focus of an image detected by an imaging substrate of an image sensor to compensate for warpage of the imaging substrate. The phased metalens can achieve a near-diffraction-limited focusing over incoming light wavelengths using precisely defined nanoscale subwavelength resolution structures.
Claims20
A system, comprising:
- a phased metalens configured to adjust a focus of an image detected by an imaging substrate of an image sensor by compensating for defocus effects caused by thermal expansion or contraction of the image sensor to enable the imaging substrate to focus the image over a range of operating temperatures.
An apparatus, comprising:
- a camera including a phased metalens configured to adjust a focus of an image detected by an imaging substrate of an image sensor of the camera by compensating for defocus effects caused by thermal expansion or contraction of the image sensor to enable the imaging substrate to focus the image over a range of operating temperatures.
A system, comprising:
- a phased metalens configured to compensate operating temperature induced warpage of an imaging substrate of an imaging sensor to adjust a focus of an image detected by the imaging substrate.
