Abstract
This project investigates the usmg of ultrasonic based tomography in flame imaging. The concentration of the flame can be measured in a pipe of rectangular shape with size of 30cm x 40cm. The project aims to obtain the cross sectional image of flame. The ultrasonic tomography measurement circuit consists of sensors, signal conditioning circuits and data acquisition system. Sensors fixture are designed based on orthogonal projection technique. In the orthogonal projection, the amount of the transmitter and receiver is same. The signal is transmitted from the transmitter to the receiver. The signal conditioning circuit is then convert the ac signal from the ultrasonic transducer to the dc voltage. Interfacing card is used to interface the analog signals from receiver circuit to the computer. The sensors detect the attenuation of acoustic energy in ultrasonic system. This provides information on the cross sectional image of the flame. To measure the concentration profile of flame, the linear back projection (LBP) technique is used. Linear back projection (LBP) algorithm has been used to perform the image reconstruction. The concentration profile is generated by combining the projection data from each sensor with its computed sensitivity map. Visual Basic 6.0 is used for software algorithms on concentration measurement. The data is collected using data acquisition system and it was an offline process.
