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.

Abstract: Disclosed herein is a method comprising: sending radiation pulses (i), i=1, . . . , M one by one toward an object and toward an image sensor as the image sensor moves nonstop in a first direction with respect to the object; and for each value of i, capturing with the image sensor a partial image (i) of the object using radiation of the radiation pulse (i) that has transmitted through the object. The image sensor comprises N active areas. Each active area of the N active areas comprises multiple sensing elements. For each value of i, the radiation pulse (i) has a pulse duration during which the image sensor travels a distance shorter than a width measured in the first direction of any sensing element of the image sensor. M and N are integers greater than 1.
