  • Publication number: 20190137386
    Abstract: In an observation method for detecting presence of a target gas, first luminance information is obtained from a background, and second luminance information is obtained from luminance radiated from the background and observed through gas to be observed. An optical member capable of transmitting electromagnetic waves in a specific wavelength band and having the same temperature as atmospheric temperature is arranged between the background and an imaging device. Luminance information for an optical image obtained without passing through the optical member and luminance information for an optical image obtained through the optical member are used and an optical image corresponding to atmospheric temperature for the observation space or the vicinity thereof and comprising blackbody radiation electromagnetic waves in a specific wavelength band is obtained as third luminance information.
