An imaging system may comprise: an image sensor; a first lens having a first field of view; a second lens having a second field of view; a multi-band pass filter capable of filtering light by allowing light having a first wavelength and light having a second wavelength to pass through; at least one cholesteric liquid crystal pair, each of the at least one cholesteric liquid crystal pairs tuned to one of the first and second wavelengths filtered by the multi-band pass filter; wherein the image sensor, the multi-band pass filter, the at least one cholesteric liquid crystal pairs, the first lens, and the second lens may be in optical communication with one another; and wherein scenes captured by at least one of the first and second lenses may be transmitted to the image sensor.

Single sensor, single path multiview or multi-band sensing

A system and corresponding method are disclosed for biometric operations. The system may comprise an illumination source, a polarization selector, an imager, and a controller. The illumination source may illuminate a biometric feature. The polarization selector may receive light reflected from the biometric feature and be operable between two states selectively transmitting different polarizations. The imager may receive the light selectively transmitted by the polarization selector and generate one or more images. The controller may perform a biometric authentication based, at least in part, on the one or more images. In operation, the polarization selector may switch between states so that the system may capture two separate image sets, each based on light of a different polarization. Accordingly, adverse reflections, such as those off an eyeball or glasses, may be substantially eliminated or reduced in at least one of the image sets.

Polarized biometric operations

An imaging system may comprise a first lens and a second lens; at least one light valve; and an image sensor in optical communication with the light valve. The first lens may be in optical communication with the light valve; and the second lens may be in optical communication with the light valve. The light valve may be configured to have a first polarization state and a second polarization state. The first polarization state may allow light to pass through the light valve and the second polarization state may reflect light that strikes the light valve.

Switchable view imaging system

A heads-up display may comprise a viewing screen having a reflective surface; a housing defining an opening; a display element disposed within the housing and comprising an integral linear polarizer configured to polarize light in a first direction; and a first linear polarizer disposed between the display element and the viewing screen covering the opening defined by the housing configured to polarize light in the first direction. The display element may be capable of causing images to be displayed on the viewing screen.
