Abstract
A gas detection device according to an embodiment includes a first irradiation part configured to irradiate a first light having a first wavelength on a gas released into a space, a second irradiation part configured to irradiate, on the gas, a second light having a second wavelength that is less than the first wavelength, an irradiation position adjustment part configured to control an irradiation position of the first light on the gas, a gas analysis part configured to analyze a component of the gas based on the first light having passed through the gas, and a gas visualization part configured to visualize a concentration distribution of the gas based on the second light having passed through the gas. The irradiation position adjustment part controls the irradiation position of the first light on the gas based on the visualized concentration distribution of the gas.
