    Abstract: A light sensor for detecting brightness of an outside of a vehicle includes: a light shielding element on a windshield; a light guiding element in a through hole of the light shielding element; and a light receiving element that receives light from the outside of the vehicle via the light guiding element and the windshield. The light guiding element includes an entrance surface facing the windshield and an output surface facing the light receiving element. The entrance surface receives the light from the outside. The light guiding element transmits and outputs the light from the output surface toward the light receiving element. The entrance surface has a top disposed inside of the through hole.

    Abstract: Aspects of the subject matter described herein relate to reducing error in images obtained from an image-acquiring system. An image-acquiring system may be modeled as light received from a primary path, light received from a secondary path, and light received from all other paths. Light received from the secondary and other paths may cause error in images captured by the image-acquiring system. By compensating for this light, the error may be reduced. Other aspects are described in the specification.

    Abstract: An imaging system for use in a vehicle headlamp control system includes an opening, an image sensor, a red lens blocking red complement light between the opening and the image sensor, and a red complement lens blocking red light between the opening 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 vehicle 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 method for determining spectral characteristics of an object is disclosed. A probe is positioned in proximity relative to the object and provides light to a surface of the object and receives light from the object. One or more critical heights are defined below which no specularly refelcted light is received and propagated. Prior to positioning the probe in proximity relative to the object, a plurality of position-sensitive calibration/normalization reference and a plurality of calibration/normalization measurements are taken with the probe at a plurality of predetermined positions with respect to the calibration/normalization reference. The intensity of light received is determined in a plurality of spectral bands with one or more measurements. The spectral characteristics of the object are determined based on the one or more measurements and based on data taken from one or more of the calibration/normalization measurements.
