An interferometric system of volume optics and fiber optic were constructed and proved, showing the instrumentation technique made for these devices, supported in the new technologies of optical detection, amplification, analogical and digital filtrate and single data acquisition. Based on the Sagnac's effect of volume optics and fiber optic, the interferometer of Sagnac has many applications, nevertheless the methods of construction, design and instrumentation for the sensors manufacture of based on both designs are not very well‐known, is for that reason that in this work approaches some of the methodologies for the design and construction of these devices, obtaining higher sensitivity and better contribution in its respective interferometric paths, for the sensing of different physical parameters in which they are applied. We used the single design for each interferometer, proposing the best detection limit for each one. The data acquisition was made with the proposal to obtain quick results, using the audio card of a PC, obtaining a real time measurements and digital processing of the signal in a single way. |
