Abstract: A light detection device includes a diffraction element and a light detection element. The diffraction element diffracts a beam of light that is incident on the diffraction element. The light detection element includes light receivers to receive diffracted light. The diffraction element generates beams of the diffracted light by dividing the beam of light. The light detection element determines a displacement of the beam of light relative to the diffraction element on the basis of quantities of light of the beams of the diffracted light. The light detection element determines an angle change of the beam of light relative to the diffraction element by dividing the quantity of light of one of the beams of the diffracted light.

Abstract: A laser beam is transmitted from a laser system to a shelving system by pointing the laser beam towards at least one label attached to the shelving system, by a computer system, using angular information of the laser beam relative to a reference frame. An angle between the laser system on the ceiling of the store to the position of the shelving system is determined by the computer system using the position of the laser system and the position of the shelving system. The laser beam is then transmitted from the laser system to the shelving system and pointed using the determined angle between the laser system on the ceiling of the store to the position of the shelving system. The laser is aimed at the x, y location where a label should be displayed, for example, according to the planogram for the store layout. If the label is not detected at the specified location, the discrepancy may be noted, for example, with a visual or other notification.

Abstract: An angle-sensitive pixel (ASP) device that uses the Talbot effect to detect the local intensity and incident angle of light includes a phase grating disposed above a photodiode assembly or a phase grating disposed above an analyzer grating that is disposed above a photodiode assembly. When illuminated by a plane wave, the upper grating generates a self-image at a selected Talbot depth. Several such structures, tuned to different incident angles, are sufficient to extract local incident angle and intensity. Arrays of such structures are sufficient to localize light sources in three dimensions without any additional optics.

Abstract: A tracking device for use when performing astrophotography comprises a guider camera and at least one tilt stage, with the topmost of the tilt stages arranged to support an astrophotography camera and the guider camera. Actuators are coupled to the tilt stages such that the astrophotography and guider cameras can be tilted about three axes. The guider camera and actuators are connected to electronics which include a computer programmed to operate in a calibration mode and a tracking mode. In calibration mode, a calibration procedure determines the effect of each actuator on the positions of at least two objects within the field-of-view (FOV) of the guider camera. In tracking mode, the actuators are operated as needed to maintain the positions of the at least two objects constant within the said FOV.

Abstract: A mobile field controller, together with a geodetic surveying device, forms a one-person measurement system for geodetic position determination. The field controller allows the spatial orientation of the field controller to be determined. The field controller supports a geodetic target object and has a distance-measuring unit that measures the distance between the field controller and a target point, the distance being optically marked by the field controller, as a result of which a 3D point cloud is generated without physical contact to a target point. When surveying a specific terrain region, algorithms analyzing the 3D point cloud are saved in a control and evaluation unit of the field controller. The absolute position of the target point is calculated from the data of the spatial orientation of the field controller, the distance between field controller and target point and the absolute position of the geodetic target object.
