چکیده
|
In this study, an optical process tomography with 2 orthogonal projections is being designed to be implemented at a vertical column modelled. the tomography system will be designed from the development of transducer pairs to the data acquisition system implemented. infrared emitters are being considered as a light source due to the difference of its wavelength with the wavelength of visible light. photodiodes are being characterized and compared for maximizing its performance when integrated with the system. microcontrollers are functioned to perform analogue-to-digital conversion. experiments are being conducted to investigate whether the system is able to detect gas bubbles in the vertical column. the results from the studies will be compared with theoretical hypotheses of light absorption and light attenuation.
