  • Optical measurement apparatus and optical measurement method
    Patent number: 12140523
    Abstract: In an optical measurement method, light is directed from a light generator to a light path cell. A light path is generated by continuously reflecting the light between first and second high reflection mirrors within a light path cell that face to each other. An optical signal is detected from an aerosol sample present within a range of the light path. The optical signal is separated into a particle signal and a gas signal by using a statistical methodology. A particle concentration is calculated from the particle signal by using an assumption of an optical particle counter (OPC). A gas concentration is calculated from the gas signal by using optical characteristic data of gas.
