SYSTEM AND METHOD FOR MONITORING ENVIRONMENTAL EFFECTS USING OPTICAL SENSORS |
摘要 |
<p>An apparatus and method for determining a physical parameter affecting an optical sensor or a number of sensors in a network. The apparatus uses a narrow linewidth source at an emission wavelength lambdae and an arrangement for varying the emission wavelength lambdae of the radiation. An analysis module with curve fitting is used to generate a fit to the response signal obtained from the optical sensor. The physical parameter is determined form the fit rather than from the response signal. The apparatus can be employed with Bragg gratings, etalons, Fabry Perot elements or other optical sensors.</p> |
