Title:
RADIATION TEMPERATURE MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/105551
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a radiation temperature measuring device with which it is possible to prevent a deterioration in temperature measurement accuracy attributable to electromagnetic waves reflected by a measured object. A radiation temperature measuring device (100) is provided with: a reflective-type polarizing plate (2) which reflects polarized light polarized in one direction, from among electromagnetic waves radiated from an object being measured, and transmits or absorbs polarized light polarized in a direction perpendicular to said one direction; and an infrared sensor (1) which detects the polarized light electromagnetic waves that have been polarized in said one direction and have been reflected by the reflective-type polarizing plate (2).
