Abstract: The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses patterned applied adhesive and a structurally weak wavelength-selective material that includes portions that contact the adhesive and break to remain in contact with the adhesive. In one embodiment, the wavelength-selective material comprises an array of sections with cuts at least partially through a wavelength-selective film at each section secured to the adhesive. In another embodiment, the wavelength-selective film comprises a transfer stack of layers.

Abstract: The disclosure describes an example vehicle assistance system including a light sensor, a pixelated filter array adjacent the light sensor, and a full-field optically-selective element adjacent the pixelated filter array. The optically-selective element is configured to selectively direct an optical component of light incident on the optically-selective element across the pixelated filter array to the light sensor.
