Title:
INTERNAL TEMPERATURE MEASUREMENT DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/218006
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve the accuracy of measurement of the internal temperature of an object. The internal temperature measurement device comprises: a sound wave sensor 1 for transmitting sound waves to an object and receiving sound waves reflected by the object; a time measurement section 20 for measuring an elapsed time between the transmission of the sound waves from the sound wave sensor 1 and the reception of the reflected waves; a sound speed calculation unit 22 for calculating a sound speed in the object on the basis of the time measured by the time measurement section 20; and an internal temperature derivation section 23 for determining an internal temperature of the object on the basis of the sound speed calculated by the sound speed calculation section 22.
