A flowmeter for measuring the dispersed phase velocity in multiphase flow with non-uniform velocity profile [PDF]
, 2008 This study aims to introduce a new technique to measure the velocity distribution of the dispersed component of a vertical, upward, water continuous two-phase pipe flow. Here, it is proposed that measurements of the variation in the local conductance

Dual-Frequency Doppler LiDAR Based on External Optical Feedback Effect in a Laser
Sensors, 2020 A novel Dual-frequency Doppler LiDAR (DFDL) is presented where the dual-frequency light source is generated by using external optical feedback (EOF) effect in a laser diode (LD). By operating a LD at period-one (P1) state and choosing suitable LD related
