Abstract

In the field of optic sensors, in most applications, the measurement of intensity is of main interest. There are many sensors, which by means of fiber optic evanescent spectroscopy are used to measure the temperature, concentration of methane or carbon dioxide in fiber optic transmission cells and glucose or other important substances. Using these sensors, the compensation of the influence at the data link dependencies is problematic. There are several proposals to compensate these influences. Among them there are the utilization of two or more wavelengths, the earliest possible digital conversion and the application of optical bridges. However, these methods are circumstantial and problems cannot be solved in general. A new method for the compensation of fiber optical connectors is presented.
