iDAS-MG offers a selection of gauge lengths to provide the best instrument performance over both short- and long-range applications. The iDAS-MG offers fine measurement resolution, unique to the balanced interferometric measurement technique of iDAS, with a wide dynamic range. Data acquisition parameters can be selected to optimally record regions of interest within the wavefield, minimizing subsequent processing and interpretation time.
iDAS-MG comprises several optical processors, embedded in a single interrogator unit. Longer gauge lengths offer better signal to noise performance over large-scale deployments, while shorter gauge lengths offer more precise small scale, high-frequency measurements. The same iDAS-MG interrogator can be deployed for sub-surface seismic imaging in oil and gas, carbon sequestration, geothermal and aquifer projects, as well as in near-surface active and passive surveys for infrastructure monitoring.
The iDAS-MG removes the ambiguity of complex signal processing, with on board data quality control and can be integrated with the Silixa Edge processing platform for continuous and time-lapse monitoring applications.
