    Abstract: An apparatus includes a light senor having directional sensitivity. The light sensor includes multiple light sensitive elements disposed below the same aperture. Each of the light sensitive elements has a respective field of view through the aperture that differs from the field of view of the other light sensitive elements. Signals from the light sensor can facilitate determining the direction of incoming light.

    Abstract: A radiation field measuring device for the characterization of a radiation comprises a detector device and a reconstruction device. The detector device may have at least one detector camera, which contains at least one detector array arranged for the image recording of scattered radiation in a multiplicity of lateral directions that deviate from the longitudinal direction. The reconstruction device may be configured for the tomographic reconstruction of a field density of the scattered radiation in the radiation field.

    Abstract: An optical system and a method of manufacturing an optical system are provided. The optical system includes a carrier, a light emitter, a light receiver, a block structure and an encapsulant. The light emitter is disposed on the carrier. The light receiver is disposed on the carrier and physically spaced apart from the light emitter. The light receiver has a light detecting area. The block structure is disposed on the carrier. The encapsulant is disposed on the carrier and covers the light emitter, the light receiver and the block structure. The encapsulant has a recess over the block structure.

    Abstract: An electro-optical assembly, in particular a sensor assembly for detecting ambient light, includes a reflection surface, a lens body and an electro-optical component, in particular a light receiver. The component includes a depression having a main lens section, in particular a diverging lens section with a concave interior wall, and a converging lens section with a convex interior wall. The interior wall of the converging lens section is formed in such a way that the rays of the ray path which travel through the converging lens section to the electro-optical component hit the reflection surface in such way that the angle of incidence at the reflection surface is larger or the same as the critical angle of the total internal reflection at the reflection surface. In another aspect a method for detecting ambient light is described.
