Dielectric mirror based multispectral filter array
Last updated:
Abstract:
An optical sensor device may include a set of optical sensors. The optical sensor device may include a substrate. The optical sensor device may include a multispectral filter array disposed on the substrate. The multispectral filter array may include a first dielectric mirror disposed on the substrate. The multispectral filter array may include a spacer disposed on the first dielectric mirror. The spacer may include a set of layers. The multispectral filter array may include a second dielectric mirror disposed on the spacer. The second dielectric mirror may be aligned with two or more sensor elements of a set of sensor elements.
