    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.

    Abstract: Various implementations relate generally to a multi-sensor device. Some implementations more particularly relate to a multi-sensor device including a ring of radially-oriented photosensors. Some implementations more particularly relate to a multi-sensor device that is orientation-independent with respect to a central axis of the ring. Some implementations of the multi-sensor devices described herein also include one or more additional sensors. For example, some implementations include an axially-directed photosensor. Some implementations also can include one or more temperature sensors configured to sense an exterior temperature, for example, an ambient temperature of an outdoors environment around the multi-sensor. Additionally or alternatively, some implementations can include a temperature sensor configured to sense an interior temperature within the multi-sensor device. Particular implementations provide, characterize, or enable a compact form factor. Particular implementations provide, characterize, or enable a multi-sensor device requiring little or no wiring, and in some such instances, little or no invasion, perforation or reconstruction of a building or other structure on which the multi-sensor device is mounted.

    Abstract: The present disclosure teaches a UV dosimeter comprising a UV-sensitive layer and a barrier that protects the UV-sensitive layer. The barrier is permeable to oxygen but impermeable to water and, thus, protects the UV-sensitive layer from water while allowing exposure of the UV-sensitive layer to oxygen. The UV-sensitive layer is accessible to both UV radiation and visible light. The UV-sensitive layer comprises a mixture of a semiconductor material, a UV-oxidizable dye, a sacrificial electron donor, and a matrix material. The semiconductor material has a band gap that corresponds to photon energy of the UV radiation. The dye has both an oxidation state and a reduction state. The oxidation state of the dye is visibly distinguishable from the reduction state of the dye. The sacrificial electron donor oxidizes when exposed to UV radiation. The matrix provides structural integrity to the mixture.

    Abstract: A proximity sensor includes a substrate, a light source, a finger electrode, an active layer, and a transparent electrode layer. The substrate has opposite top and bottom surfaces. The light source faces toward the bottom surface of the substrate. The finger electrode is located on the top surface of the substrate, and has finger portions and gaps between every two adjacent finger portions. The active layer covers the finger electrode, and is located in the gaps. The transparent electrode layer is located on the active layer. When the light source emits light, the light through the gaps sequentially passes through the active layer and the transparent electrode layer onto a reflective surface. The light is reflected by the reflective surface to form reflected light, and the reflected light passes through the transparent electrode layer and is received by the active layer.
