摘要： 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.

摘要： 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.

摘要： The invention shows a sensor for measuring diffuse solar irradiance including: an hemisphere having an approximately 2π steradian solid opening angle with a non-transparent layer and a transparent aperture pattern, the transparent aperture pattern providing a near-uniform transmission of the diffuse radiation as seen from near a center of the hemisphere, an aperture being an area occupying a part of the hemisphere surface area that is smaller than 2% and two or more light-sensitive sensors arranged in an array near the center of the hemisphere such that under any position of the sun relative to the sensor at least one of the two or more light-sensitive sensors is shaded from direct solar radiation by the hemisphere with aperture pattern.

摘要： An optical sensor module and a packaging method thereof are disclosed, wherein the optical sensor module comprises a substrate having a light sensing element; and a housing made of a transparent material. The housing is connected to the substrate and covers the light sensing element. The housing has a light-receiving area facing the light sensing element, and the inner surface of the housing toward the substrate is provided with a light-shielding coating in a portion outside of the light-receiving area. In this way, optical components such as the light sensor can be effectively protected, and still retain the effect of avoiding noise light interference with the light sensor module.

摘要： Example embodiments include an optical interrogation system with a sensing fiber having a single core, the single core having multiple light propagating modes. Interferometric apparatus probes the single core multimode sensing fiber over a range of predetermined wavelengths and detects measurement interferometric data associated with the multiple light propagating modes of the single core for each predetermined wavelength in the range. Data processing circuitry processes the measurement interferometric data associated with the multiple light propagating modes of the single core to determine one or more shape-sensing parameters of the sensing fiber from which the shape of the fiber in three dimensions can be determined.
