摘要： An optical sensor device comprises a first and a second optical sensor arrangement. In the first optical sensor arrangement at least one optical sensor structure measures the incidence angle of incoming light that is approximately on the main beam axis of a light source. The second optical sensor arrangement comprises at least one optical sensor structure with at least one optical sensor, at least two metal layers and opaque walls optically isolating the optical sensor. An evaluation circuit provides an output signal of the second optical sensor arrangement under the condition that the incidence angle measured by the first optical sensor arrangement lies within a set interval.

摘要： In a method for determining orientation of an object, raw image data of the sky is recorded using a sky polarimeter. One or more of Stokes parameters (S0, S1, S2), degree of linear polarization (DoLP), and angle of polarization (AoP) are calculated from the image data to produce a set of processed images. Last known position and time data of the object are obtained, and a known Sun azimuth and elevation are calculated using the last known position and time data. Roll and pitch of the object are found, and the roll and pitch data are used to find a zenith in the processed images. The yaw/heading of the object is determined using the difference between a polarization angle at the zenith and a calculated Sun azimuth.

摘要： A system for detecting a direction of a source of a laser beam includes a pixelated sensor that is sensitive to the laser beam. A mask is disposed between the source of a laser beam and the pixelated sensor. The mask includes an opaque portion that is opaque to the laser beam and a window portion that is at least translucent to the laser beam. When the laser impinges upon the mask an image of the window portion is projected onto the pixelated sensor. A processor determines an angle of incidence of the laser beam with respect to the mask by determining a number of pixels that the image of the window is offset from where the image of the window would be if the laser beam had been normal to the mask.

摘要： An optical encoder configuration comprises a scale, an illumination source, and a photodetector configuration. The illumination source is configured to output structured illumination to the scale. The scale extends along a measuring axis direction and is configured to output scale light that forms a detector fringe pattern comprising periodic high and low intensity bands that extend over a relatively longer dimension along the measuring axis direction and are relatively narrow and periodic along a detected fringe motion direction transverse to the measuring axis direction. The high and low intensity bands move along the detected fringe motion direction transverse to the measuring axis direction as the scale grating displaces along the measuring axis direction. The photodetector configuration is configured to detect a displacement of the high and low intensity bands along the detected fringe motion direction and provide respective spatial phase displacement signals that are indicative of the scale displacement.

摘要： An electronic device includes a housing, one or more processors, and one or more proximity sensor components, each having an infrared signal receiver to receive an infrared emission from an object external to the housing. The proximity sensor component is disposed by a first aperture and a second aperture, the first aperture having a first axis oriented in a first direction and the second aperture having a second axis oriented in a second direction. Attenuation of infrared emissions can occur through one of the first aperture or the second aperture. The one or more processors can determine whether a received infrared emission is attenuated to detect whether the received infrared emission was received from the first direction or the second direction.
