Open the CIPO recordAbstract From the Canadian patent
A method and aparatus for spectroscopic gas analysis are provided. Two coherent beams of monochromatic radiation are directed through gaseous material. A tuning mechanism adjusts the frequency difference between the radiation beams to equal substantially the rotational frequency of a preselected constituent of the gaseous material. Radiation scattered by the gaseous material is received by a filtering mechanism adapted to transmit selectively an anti- Stokes signal generated coherently during scattering. The signal is received by a detecting mechanism which indicates the intensity thereof.

Why it's free to use
- Granted December 18, 1979. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended December 18, 1996.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
