NON-CONTACT GAS MEASUREMENT DEVICE, NON-CONTACT GAS MEASUREMENT SYSTEM, AND NON-CONTACT GAS MEASUREMENT METHOD

摘要

To measure gas from an object with a simple configuration without affecting a skin of a user and the like.SOLUTION: In a non-contact gas measurement device 100, a reception oscillation unit 101 is configured to conduct emission and detection of an electromagnetic wave. A visible light source 104 is configured to emit an electromagnetic wave different from that to be emitted by the reception oscillation unit 101. An optical element 107, of which transmittance changes based on the electromagnetic wave to be emitted by the visible light source 104, is configured to transmit or reflect the electromagnetic wave to be emitted by the reception oscillation unit 101. A control unit 110 is configured to, upon measuring an object, control so as to: cause the electromagnetic wave of the visible light source 104 to be halted; cause the transmittance to be changed so that the optical element 107 serves as a transmissive plate; and cause the object to be irradiated with the electromagnetic wave transmitting the optical element 107. The reception oscillation unit 101 is configured to output a value of a voltage or electricity varying in responce to intensity of the electromagnetic wave reflected from the object 600 as a measurement value.SELECTED DRAWING: Figure 18
