| 總結: | This research investigates the methods of implementing switch mode parallel beam projection technique into optical tomography instrument, and observes the effects of lens in optical system tomography. In addition, the research is focused on measuring the maximum size of phantom that can be captured for concentration profile. There are two types of sources that are used in tomography system which are high and low radiation sources. In this research, low radiation source is used as a medium to measure phantom inside the pipe. There are many types of components that produce light including the light-emitting diode (LED), infrared and laser. The tests are done using laser. Pipe has 100 mm inner diameter and the convex lens is applied in front of light component to change the angle of the transmitted light. The received light is captured by the sensor for further analysis to determine phantom inside the pipe region. Result shows that the optical tomography combine with lens is easier to manage the coverage of region. The results indicate that the proposed system is suitable for object application range between 8 mm to 80 mm. |
