Устройство для измерения температуры расплавленных материалов

Номер: RU0000189043U1
Автор: Александр Николаевич Забродин, Юрий Витальевич Гордеев
Принадлежит: Александр Николаевич Забродин, Юрий Витальевич Гордеев

Полезная модель устройства для измерения температуры расплавленных материалов относится к измерительной технике. Устройство для осуществления измерения температуры расплава содержит погружной зонд с огнеупорным кварцевым световодом, установленным в огнеупорную втулку, запрессованную в картонную трубку. При этом конец кварцевого световода выступает из керамической втулки на определенную длину и его кончик покрыт огнеупорным оптически не прозрачным материалом с известным коэффициентом теплового излучения. Перед измерением зонд надевается на полый металлический жезл, внутри которого расположена оптоволоконная линия, соединяющая внутренний торец световода с приемником излучения. При погружении зонда в емкость с расплавом в течение короткого времени расплав разогревает кончик кварцевого световода и его тепловое излучение через световод и оптоволоконную линию передается к приемнику излучения. Технический результат - повышение точности измерения температуры расплава различных веществ вне зависимости от их коэффициента теплового излучения. 1 ил.

A mechanism of quantitative dual-spectrum IR imaging (QDS-IR) system for examining the breast cancer is reported. The major mechanism of the system is a pair of long-wave Infra-red (LIR) and middle-wave Infra-red (MIR) cameras with the keen temperature sensitivity and the high spatial resolution. The optical axes of cameras are calibrated by the help of two calibration makers set up on the seat for carrying an object to make them parallel to each other and locate on the same level. The design provides an imaging system with the high reproducibility supported by 7 free degrees and the high adjustability. The proposed system could ensure the positions of the object and two cameras are the same at the different time points and find the best relative positions between the seat and two cameras for the objects with different body types. Therefore, it has potential ability to detect breast cancer or monitor the effect of chemotherapy.

In conventional membrane infrared (IR) sensors, little to no attention has been paid toward transmissivity of IR near metal traces. Here, because the substrate of an integrated circuit carrying the sensor is used as a visible light filter, reflection of IR radiation back into the substrate can affect the operation and reliability of the IR sensor. As a result, an arrangement is provided that reduces the area occupied by metal lines by reducing the pitch and compacting the routing so as to reduce the effects from the reflection of IR radiation by metal traces. 1.

Method and apparatus for measuring temperature of a measured area of a surface without contacting the surface. The thermometer apparatus has an optical system which generates a correlative image of an infrared energy detector sensitive area at an image distance from the thermometer. A limiting aperture, having a size and a shape corresponding to those of the generated image, is between a mirror and the generated image. The measured area of the surface is between the generated image and the thermometer in use. With such a configuration, little infrared energy that does not originate from the measured area strikes the detector. Consequently, the energy reaching the detector is limited such that the size of the measured area remains constant, regardless of changes in the thermometer's field of view attributable to differences in the distance between the surface and the thermometer. A scan-and-integrate mode for practicing the invention is disclosed.
