…Unlike the photon effect type, the wavelength sensitivity characteristic for the light power is almost flat, and it is possible to make one that operates at room temperature even in the long wavelength infrared region. Detectors are characterized by the thermal-electrical conversion section, and thermocouples and thermopiles using thermocouple thermometers, bolometers using resistance thermometers, Golay cells using gas thermometers, and pyroelectric detectors using the pyroelectric phenomenon are in practical use. (3) Wave interaction type These utilize the phenomenon in which the electromagnetic properties of light directly induce interaction with matter, and include optical heterodyne detectors, parametric detectors, and Josephson detectors. … *Some of the terminology that mentions "Golay cell" is listed below.

…光子効果型と異なり光のパワーに対する波長感度特性がほぼ平たんであり,長波長赤外域においても常温動作のものを作りうる点が特徴である。検出器は熱‐電気変換部によって特徴づけられ,熱電対温度計を用いた熱電対や熱電堆,抵抗温度計を用いたボロメーター,気体温度計を用いたゴレーセルGolay cell,焦電現象を利用した焦電検出器pyroelectric detectorなどが実用されている。(3)波動相互作用型 光の電磁波としての性質が直接物質との相互作用を誘起する現象を利用したもので,光ヘテロダイン検出器,パラメトリック検出器,ジョセフソン検出器などがある。… ※「Golay cell」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
