Abstract (EN): A digital control system to interrogate optical fiber interferometric sensors is presented. The system was implemented using a DAQ board and LabView Software, it is based on white light interferometry, and can use four different synthetic heterodyne and pseudo-heterodyne signal detection schemes. The system was tested and compared with standard hardware instrumentation using a fiber optic Mach-Zehnder interferometer to readout strain sensitive Fabry-Perot sensors in a differential configuration. It is shown that the virtual instrumentation has a good performance being a viable alternative for use in compact portable sensing systems.
