Abstract:
The instant disclosure provides a large-area laser heating system including a laser module, a reaction module and a guiding module. The laser module includes a vertical-cavity surface-emitting laser for emitting a laser beam and a laser adjusting structure connected to the vertical-cavity surface-emitting laser. The incident angle of the laser beam emitted by the vertical-cavity surface-emitting laser is adjusted by the laser adjusting structure. The reaction module includes a sample holder for carrying a sample. The guiding module is connected between the laser module and the reaction module, and the laser beam emitted by the vertical-cavity surface-emitting laser passes through the guiding module and projects onto the surface of the sample.
Abstract:
A bolometric detection device includes a substrate having a read-out circuit. The device also includes an array of elementary detectors each including a membrane suspended above the substrate and connected to the read-out circuit by at least two electric conductors. The membrane has two electrically-conductive electrodes respectively connected to the two electric conductors, and a volume of transducer material electrically connecting the two electrodes. The read-out circuit is configured to apply an electrical stimulus between the two electrodes of the membrane and to form an electric signal as a response to said application. The volume includes a volume of a first transducer material electrically connecting the two electrodes of the membrane and forming walls of a closed enclosure having each of the electrodes at least partially housed therein; and a volume of a second transducer material, electrically connecting the two electrodes and housed in the enclosure, the electric resistivity of the second material being smaller than the electric resistivity of the first material; and the two transducer materials having a negative thermal coefficient of resistivity TCR.
Abstract:
Methods and systems for performing non-contact temperature measurements of optical elements with long wavelength infrared light are described herein. The optical elements under measurement exhibit low emissivity to long wavelength infrared light and are often highly reflective or highly transmissive to long wavelength infrared light. In one aspect, a material coating having high emissivity, low reflectivity, and low transmission at long wavelength IR wavelengths is disposed over selected portions of one or more optical elements of a metrology or inspection system. The locations of the material coating are outside the direct optical path of the primary measurement light employed by the metrology or inspection system to perform measurements of a specimen. Temperature measurements of the front and back surfaces of an IR-transparent optical element are performed with a single IR camera. Temperature measurements are performed through multiple optical elements in an optical path of a primary measurement beam.

Provided is an infrared sensor which is capable of measuring a temperature of an object to be measured with high accuracy even when lead wires are connected to one side thereof. The infrared sensor includes an insulating film; a first and a second heat sensitive element which are provided on one face of the insulating film; a first and a second wiring film that are respectively connected to the first and the second heat sensitive element; an infrared reflecting film; a plurality of terminal electrodes; and a thermal resistance adjusting film which is provided on the other face of the insulating film, is in opposition to at least a portion of the longer one of the first or the second wiring film in wiring distance from the terminal electrodes, and is formed of a material with greater heat dissipation than the insulating film.

An infrared detecting arrangement includes an infrared detecting element (10) having a heat insulating film (13) and an infrared detector (14) which are disposed between an interior space of a hermetically sealed casing (18) for the element and a cavity (11) formed within a substrate (12) of the element and communicating through a ventilator (19) with the interior space (17). In an infrared detecting device of this arrangement, any gas pressure difference between the interior space and the cavity can be remarkably effectively reduced to attain an extremely excellent sensitivity.

The present publication describes a heat-resistant optical layered structure, a manufacturing method for a layered structure, and the use of a layered structure as a detector, emitter, and reflecting surface. The layered structure comprises a reflecting layer, an optical structure on top of the reflecting layer, and preferably shielding layers for shielding the reflecting layer and the optical structure. According to the invention, the optical structure on top of the reflecting layer comprises at least one partially transparent layer, which is optically fitted at a distance to the reflecting layer.
