Title:
NONCONTACT GAS MEASUREMENT DEVICE, NONCONTACT GAS MEASUREMENT SYSTEM, PORTABLE TERMINAL, AND NONCONTACT GAS MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2019/117032
Kind Code:
A1
Abstract:
The present invention measures a gas from an object by means of a simple configuration thereof, without influencing the skin of a user and the like. In a noncontact gas measurement system 500 according to the present invention, a noncontact gas measurement device 100 measures a gas 601 to be measured, which is generated from an object 600, by using an electromagnetic wave. An analysis unit 410 analyzes the gas 601 to be measured, from a measurement value measured by the noncontact gas measurement device 100. The noncontact gas measurement device 100 is provided with a signal receiving oscillation unit and a control unit. The signal receiving oscillation unit outputs and detects an electromagnetic wave. The control unit controls the signal receiving oscillation unit. The signal receiving oscillation unit outputs, to the analysis unit 410, a value of a voltage or a current which changes in response to an intensity of an electromagnetic wave reflected from the object 600 after the electromagnetic wave is irradiated onto the object 600 as a measurement value, on the basis of an instruction of the control unit.
