Abstract: The description relates to capturing or sensing color images of scenes and information about the type of light (e.g., light source) that illuminated the scene. One example can include an image sensor manifest as an array of pixels. This example can also include a lens configured to focus an image from a scene on the array of pixels. The array of pixels can entail first pixels that are configured to sense the image and second pixels that are configured to capture information about lighting of the scene.

Abstract: A spectral device includes a polarizing filter and an optical filter. The polarizing filter transmits part of light incident on the polarizing filter, the part of light having a particular polarization component. Light that is incident on and passes through the polarizing filter is converted into linearly polarized light. Light that has passed through the polarizing filter is incident on the optical filter. The optical filter transmits light within a particular frequency range. The optical filter includes a metal layer and a dielectric layer. The dielectric layer is disposed on the metal layer. Multiple slits are formed in the metal layer. The multiple slits are arranged at equal intervals in a predetermined direction. The multiple slits extend in a direction perpendicular to a direction in which the light that has passed through the polarizing filter is polarized.

Abstract: A device such as a filter or reflector includes a conductive layer including a periodic pattern of elements. The elements have shapes and sizes configured such that a transmittance or reflectance spectrum of the conductive layer has a drop at a long-wavelength end. The elements have a period configured such that the spectrum has a dip at a Plasmon mode resonant wavelength. The spectrum further includes a peal—between the dip and the drop.
