PROBLEM TO BE SOLVED: To provide an infrared radiation element capable of efficiently applying infrared radiation.SOLUTION: An infrared radiation element 1 comprises: a substrate 2; a thin film 3 formed over one surface of the substrate 2; a through hole 2a which goes through in a thickness direction of the substrate 2; a lattice-like first infrared radiation 4a formed at the opposite side of the substrate 2 in the thin film 3. The infrared radiation element 1 also comprises: plural pads 9 which are electrically connected to the first infrared radiation layer 4a; and a second infrared radiation layer 4b which is disposed separated away from the radiation layer 4a in an opening 4aa of the first infrared radiation layer 4a and which has the infrared radiation ratio higher than that of the thin film 3.
Abstract:
A system for calibrating a sensor in a vehicle, such as a space capsule or another space borne apparatus, uses an expandable integrating sphere. A sensor in the vehicle measures the energy from an electromagnetic energy source within the integrating sphere through a calibration window. The expandable fluid impermeable integrating sphere expands when filled with a fluid, such that when filled with the fluid, its interior is viewable through the calibration window. The system includes a source of fluid to fill the integrating sphere and a fluid regulator coupled to the vehicle to determine when to supply the fluid to the integrating sphere to maintain an appropriate gas pressure level with the integrating sphere.

PROBLEM TO BE SOLVED: To provide an optical identification module device and an optical reader, which can reduce the volume of the optical reader and also reduce the cost and processing time.SOLUTION: A light source container and a guiding recess are arranged on one side of a light pipe. A first light channel is defined in the light pipe. An engaging bump and a separating bump are arranged on one side of a lens holder. The engaging bump engages with the guiding recess. A second light channel corresponding to the first light channel is defined in the lens holder, and a lens is arranged in the second light channel. A sensing circuit board with a receiver soldered at a position corresponding to the second light channel is arranged at the bottom of the lens holder. A light emitting diode is placed in the light source container.
Abstract:
A light radiation device that radiates light with a desired spectrum and controlled directivity is provided. A light radiation device (100) according to the present invention includes: a light source (101); an optical waveguide (107); and a spectrum modulating member (104), the optical waveguide (107) guiding incident light from the light source (101) thereinto through a plane of incidence, causing the light to be reflected by sides of the optical waveguide (107), and emitting directivity-controlled light through a plane of emission, the spectrum modulating member (104) attenuating a spectrum in a particular band of wavelengths among the directivity-controlled light, the optical waveguide (107) becoming narrower from the plane of emission toward the plane of incidence, the spectrum modulating member (104) being provided toward the plane of emission of the optical waveguide (107).
