Infrared Technology

赤外線（IR）温度計は、測定対象物が放射する赤外線を検出して数値化することで温度を決定するセンサです。IR温度計は、人の目に例えることができます。目のレンズ（水晶体）は、物体からの放射（光子の流れ）が大気を経て、感光層（網膜）に至るまでの光学系と言えます。これが、信号となって脳に伝えられます。図3は、赤外線測定システムがどのように働くかを示しています。

Check the Raytek GS110 glass process imaging system in the production quality control of coated glass, low emission flat glass and architectural glass. With non-contact IR sensors, you can analyze the temperature distributions in the area, identify defective heating elements, automatically adjust the emissivity to change glass loads, identify defective heating elements and manage the heat balance in the glass oven.

The optical system of an infrared sensor collects the infrared energy from a circular measurement spot and focuses it on the detector. Optical resolution is defined by the ratio of the distance from the instrument to the object, compared to the size of the spot being measured (D:S ratio). The larger the ratio number the better the instrument's resolution, and the smaller the spot size that can be measured from greater distance.

Emissivity is the measure of an object's ability to emit infrared energy. Emitted energy indicates the temperature of the object. Emissivity can have a value from 0 (shiny mirror) to 1.0 (blackbody). Most organic, painted, or oxidized surfaces have emissivity values close to 0.95. The majority of our IR sensors have an adjustable emissivity feature to ensure accuracy when measuring other materials, such as shiny metals.

These are the most frequent asked questions and answers about Infrared Sensors.
