invisensing : sensing beyond and beyond sensing
Real-time data processing
DAS interrogator produces massive amount of raw data over time. We develop efficient data stream management algorithm to handle the data flow and computations promptly. The low-noise digital demodulation algorithm permits a high-fidelity acoustic waveform retrieval. The multi-component acoustic field picked up by the sensor is exploited to map the pressure distribution along the sensing cable. We also establish AI-assisted algorithm for flow rate or production prediction based on the collected acoustic field.
