Transmission/Reflection Dual-Mode Ultrasonic Tomography Using Weighted Least Square-Lagrange Joint Reconstruction

FPGA-Accelerated Distributed Sensing System for Real-Time Industrial Laser Absorption Spectroscopy Tomography at Kilo-Hertz

“…To comprehensively characterize the industrial processes, industrial process tomography (IPT) techniques have been widely developed for acquiring two/three-dimensionally distributed parameters [4]. Depending on different sensing modalities, the IPT techniques generally involve ultra-sensitive measurement of multi-channel electrical [5], ultrasonic [6], optical signals [7], via signal modulation/demodulation techniques to improve the measurement Signal-to-Noise Ratio (SNR). Furthermore, most IPT applications require continuous imaging of the industrial processes with penetrating temporal resolution, placing significant requirement on the high-speed DAQ and real-time data communication between the front-end sensors and backend high-level processors.…”
