Abstract

A method and apparatus for measuring density which can simultaneously measure gaseous substance density and solid particulate material density and further can simultaneously measure the densities of a plurality of materials such as black smoke, white smoke, and water vapor. The method includes irradiating a laser having at least one wavelength equivalent to an absorption wavelength of each gaseous substance to be measured.
