| 摘要 |
<p>The invention concerns a method for controlling the quality of a product treated at a temperature and under an atmosphere generated by burners arranged at certain locations of the oven (11) wherein the products to be treated (13) move past, by means of a laser diode (14) whereof the laser beam passes through the atmosphere of the oven, the optical characteristics of the beam being modified after passing through the oven (12). The analysis of the modifications of the beam (15) which passes proximate to the treated products enable to act immediately on the fluid (oxidant/fuel) injections in the burners to modify said atmosphere and thereby control the quality of the products. The invention is applicable to heating ovens.</p> |
