Abstract: An imaging system for use in a vehicle headlamp control system includes an aperture, an image sensor, a red lens blocking red complement light between the aperture and the image sensor, and a red complement lens blocking red light between the aperture and the image sensor. Each lens focuses light onto a different subwindow of the image sensor. The imaging system allows processing and control logic to detect the presence of headlamps on oncoming vehicles and tail lights on vehicles approached from the rear for the purpose of controlling headlamps. A light sampling lens may be used to redirect light rays from an arc spanning above the vehicle to in front of the veicle into substantially horizontal rays. The light sampling lens is imaged by the image sensor to produce an indication of light intensity at various elevations. The processing and control logic uses the light intensity to determine whether headlamps should be turned on or off. A shutter may be used to protect elements of the imaging system from excessive light exposure.

Abstract: A technique of determining the presence of a species in a sample may include passing light through an optical filter. In an example, the optical filter may include a spatially variant microreplicated layer optically coupled to a wavelength selective filter. The wavelength selective filter may have a light incidence angle-dependent optical band. The spatially variant microreplicated layer may be configured to transmit light to a first optical region of the wavelength selective filter at a first predetermined incidence angle and to a second optical region of the wavelength selective filter at a second predetermined incidence angle.

Abstract: A radiation-sensitive device configured to determine an ambient radiation intensity is disclosed. The device includes at least one set of optical filters comprising: a first optical filter having a first passband spanning a portion of a spectrum associated with a radiation-emitting device and a portion of an ambient radiation spectrum; and a second optical filter having a second passband spanning a portion of the spectrum associated with the radiation-emitting device and a portion of the ambient radiation spectrum, the second passband different to the first passband. The device also includes processing circuitry configured to determine, from an intensity of incident radiation sensed using the first and second optical filters and based on the spectrum associated with the radiation-emitting device, a contribution of ambient radiation to the intensity of incident radiation sensed using the first and second optical filters.
