Abstract
An optical device may comprise an array of sensor elements that includes a plurality of pixels and a multispectral filter disposed on the array of sensor elements. The multispectral filter may be configured to pass a first transmission percentage of light of a particular spectral range to a first set of pixels of the plurality of pixels and pass a second transmission percentage of light of the particular spectral range to a second set of pixels of the plurality of pixels.
Claims22
An optical device comprising:
- a plurality of optical channels comprising an optical channel,
- the optical channel comprising:
- a first section configured to pass a first transmission percentage of light of a particular spectral range, and
- a second section configured to pass a second transmission percentage of light of the particular spectral range,
- wherein the second transmission percentage is different from the first transmission percentage.
