Two interferometric systems were built, one in bulk optics and other one in fiber optics for showing the instrumentation stage designed for these devices, supported in a photodetector. This stage has a circuit for amplification, analog filtering and software for single channel data acquisition and digital filtering. Based on the Sagnac effect in bulk optics and in fiber optics, the Sagnac interferometer has many applications, nevertheless the methods of construction, design and instrumentation for the sensors used on both types of interferometers are well-known, but very common or general form, for this reason 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. We used the simplest design for each interferometer, proposing the best detection limit for each one; to obtain the previous thing, we implement the three previous steps: amplifiers and analogous filters, software for filtering the digital sign. The data acquisition method used to allow us to obtain faster results, using the card of a PC, getting real time measurements and digital processing of the signal.
