Method of measuring low concentrations of a light absorbing component |
摘要 |
A laser beam is transmitted through a medium containing the component to be measured. The wavelength of the beam is such that it is absorbed by the component but not by the remainder of the medium. The divergence of the beam is measured to indicate a change in the index of refraction of the medium due to the absorption by the component.
