Hardware Design of Laser Optical Tomography System for Detection of Bubbles Column

Abstract: This paper presents a hardware design and optical tomography application for fast cross sectional detection of single or two phase flows in pipes or bubble columns. Sixteen laser pointer transmitters and photodiode receivers are arranged at the object cross sectional boundary to detect the existence of bubbles inside a vertical column pipeline. A valve is installed at the bottom of the pipe to produce the source of bubbles. Due to the simple operation, good heat transfer and mass transfer of bubble columns, th… Show more

“…Here, the minimum size of gas that could be detected by the system was 20 mm. However, in 2013, Mohd Fadzil et al [18] proposed optical tomography for a vertical bubble column (130 mm in outer diameter and 1.2 m in length). Here, sixteen laser pointers and sixteen photodiode model EPD-660-5 were chosen as transmitters and receivers, respectively.…”

“…Tomography systems that use computers to reconstruct the images are called Computed Tomography (CT). This is because the tomography systems developed are using computers to reconstruct the images [2][3][4][5][6][7] . The hardware designs developed are call Data Acquisition Systems (DAS) that can be connected to the computers for data processing of image reconstruction.…”
