Abstract: The invention relates to a light grid having divergent light beams so that cross-beams can also be evaluated beside parallel beams, wherein not only a light beam interruption, but also the intensity of the light incidence on a light reception unit is evaluated.

Furthermore, each beam contains an effective beam, with an effective beam being defined in that a part shading of this effective beam effects a measurable intensity change in the associated light receiver corresponding to the shading. Finally, the effective beams define at least one detection zone in the monitored plane, with an illumination by at least one effective beam being present in the total detection zone.

Abstract: An image sensor with an array of image sensor pixels is provided. Each image pixel may include a photodiode and associated pixel circuits formed in the front surface of a semiconductor substrate. Buried light shielding structures may be formed on the back surface of the substrate to prevent pixel circuitry that is formed in the substrate between two adjacent photodiodes from being exposed to incoming light. The buried light shielding structures may be lined with absorptive antireflective coating material to prevent light from being reflected off the surface of the buried light shielding structures. Forming buried light shielding structures with absorptive antireflective coating material can help reduce optical pixel crosstalk and enhance signal to noise ratio.
