Abstract: A spectroscopic sensor includes a wiring substrate having a main surface, a light detector disposed on the main surface of the wiring substrate, a Fabry-Perot interference filter, a spacer which is provided on the main surface of the wiring substrate and supports the Fabry-Perot interference filter so that the Fabry-Perot interference filter and the light detector are separated from each other, and a stem connected to a ground potential. A second current path which has a smaller electric resistance than that of an arbitrary first current path which extends from the Fabry-Perot interference filter to the light detector via the spacer and the wiring substrate is formed between the Fabry-Perot interference filter and the stem.

Abstract: The present invention introduces a high-power beam profiling system with versatile beam sampling capabilities, designed specifically for measuring multi-kilowatt laser beams. To overcome the limitations of traditional sampling devices that scan the laser beam for measurements, my invention employs a rotating beam sampler. This sampler swiftly traverses the beam for a brief period, capturing a momentary sample which is then reflected to a preferred measuring device such as a camera beam profiler. By capturing a snapshot of the beam, the camera determines the beam size efficiently. The device is inherently cooled by the rotating sampler's movement in the air, coupled with the assistance of external cooling nozzles. It comprises a low-reflectivity mirror, a mechanical arrangement for precise positioning of the mirror, a rotating motor, an additional low-reflectivity mirror, a beam profiling camera, and the necessary micro-controller and algorithm for image processing and calculating the beam profiles.

Abstract: A sunshine recorder has: a lens that emits, as projection light, natural light incident from half of the celestial sphere; a sensor that photoelectrically converts the projection light projected onto a light receiving surface, and outputs the photoelectrically converted projection light; and a determination circuit that determines the presence or absence of sunshine on the basis of an output of the sensor, wherein the sensor has a plurality of detection areas on the light receiving surface and is configured to output a signal corresponding to the intensity of the projection light incident on each of the detection areas, and the determination circuit removes a scattered light component included in the projection light on the basis of a difference operation of the signal output from each of the detection areas to extract only a direct light component to be included in the projection light at the time of incidence of sunlight.

Abstract: An integrated circuit that includes a substrate, a photodiode, and a Fresnel structure. The photodiode is formed on the substrate, and it has a p-n junction. The Fresnel structure is formed above the photodiode, and it defines a focal zone that is positioned within a proximity of the p-n junction. In one aspect, the Fresnel structure may include a trench pattern that functions as a diffraction means for redirecting and concentrating incident photons to the focal zone. In another aspect, the Fresnel structure may include a wiring pattern that functions as a diffraction means for redirecting and concentrating incident photons to the focal zone. In yet another aspect, the Fresnel structure may include a transparent dielectric pattern that functions as a refractive means for redirecting and concentrating incident photons to the focal zone.

Abstract: A single photon number resolving detector provides photon number resolution. The detector includes a waveguide which receives photons for detection. Nanowires are located in proximity to the waveguide. Each of the nanowires is connected in series with an electrically resistive component to provide a branch. Plural branches are electrically connected in parallel with one another. A power source is connectable to deliver an electrical current to flow through the branches. A current monitor is connected to monitor a magnitude of the total electrical current in the plurality of branches. At an operating temperature of the detector the nanowires are superconducting and each branch has an electrical time constant which is small enough to cause latching of the branch to a latched state when the nanowire of the branch absorbs a photon from the waveguide. The number of photons detected can be determined from the magnitude of the current which depends on the number of branches in the latched state.
