Optical tomography: Velocity profile measurement using orthogonal and rectilinear arrangements

In tomography applications, flow velocity is an important flow characteristic for analysis. Excessively high particle velocity will cause high energy consumption, severe pipeline wear and particle degradation. This paper demonstrates a method of measuring velocity profile using the orthogonal and rectilinear sensors. Several experiments have been conducted to measure the velocity using those sensors and the results will be described at the end of the paper.

► We develop orthogonal and rectilinear optical tomography sensors.
► We measure the velocity profile of solid and particles in a vertical column.
► Velocity profile using pixel to pixel and sensor to sensor correlations is collected.
► Both correlation methods offer results close to another.
