摘要

提出了一种非接触式三谱测温方法。使用了三个硅光电二极管。光谱的分离是由光带通滤波器和分束器完成的。可以在三种模式下工作:三光谱，两光谱(光谱比)和一光谱。在第一种模式下，可以测量具有未知和可变发射率的物体的温度。后两种模式分别对灰体和已知发射率的物体具有较好的效果。

DEVELOPMENT OF A METHOD FOR CONTACTLESS TEMPERATURE MEASUREMENT IN 3 SPECTRAL RANGES

A 3-spectral method for non-contact temperature measurement has been developed. Three silicon photodiodes were used. The separation of the spectrum is done by optical bandpass filters and beamspliters. It is possible to work in three modes: three-spectral, two-spectral (spectral ratio) and one-spectral. In the first mode, the temperature of objects with an unknown and variable emissivity can be measured. The last two modes give good results respectively for gray bodies and for objects with known emissivity.
