Abstract
An optical system includes a multispectral sensor; an optical filter including a plurality of optical channels that is disposed over the multispectral sensor; and a lens that is disposed over the optical filter. The lens is configured to direct first light that originates from a scene to the optical filter. The optical filter is configured to pass one or more portions of the first light to the multispectral sensor. The multispectral sensor is configured to generate, based on the one or more portions of the first light, spectral data associated with the scene.
Claims20
An optical system, comprising:
- a multispectral sensor including a plurality of multispectral sensor elements;
- an optical filter including a plurality of optical channels that is disposed over the multispectral sensor;
- a lens that is disposed over the optical filter;
- and
- an image sensor including a plurality of image sensor elements, wherein:
- the lens is configured to direct first light that originates from a scene to the optical filter,
- the optical filter is configured to pass one or more portions of the first light to the multispectral sensor,
- the multispectral sensor is configured to generate, based on the one or more portions of the first light, spectral data associated with the scene, and
- the image sensor is configured to generate image data based on second light that originates from the scene.
An optical system, comprising:
- an optical filter including a plurality of optical channels that is disposed over a multispectral sensor;
- and
- a lens that is disposed over the optical filter, wherein:
- the lens is configured to direct first light that originates from a scene to the optical filter,
- the optical filter is configured to pass one or more portions of the first light to the multispectral sensor to permit the multispectral sensor to generate spectral data associated with the scene that can be used to determine white balance information associated with the scene.
An optical filter, comprising:
- a plurality of optical channels that includes:
- a first set of one or more optical channels that are configured to have a first transmittance level that is greater than or equal to 90% for light associated with a spectral range;
- a second set of one or more optical channels that are configured to have a second transmittance level that is less than or equal to 7% for light associated with the spectral range;
- and
- a plurality of other sets of one or more optical channels,
- wherein a particular set of one or more optical channels, of the plurality of other sets of one or more optical channels, are configured to have a particular transmittance level that is greater than or equal to 20% for light associated with a particular spectral subrange of the spectral range.
