Abstract

This project is to design, implement and compare infra red based tomography system which using orthogonal and fan beam projection. Here, the basic concept of orthogonal and fan beam projection must be understood. Infra red will be used as the light emitter and receiver sensor in this project. In terms of hardware, two types of jig/fixture will be designed in order to comparing orthogonal and fan beam projection. The reconstructed images from these two types of projections (orthogonal and fan beam) can be formed by design a signal conditional circuit and fabricate into printed circuit board (PCB) and the data from this circuit will be transferred through Data Acquisition (DAQ). Besides the hardware, this project will include the use of user friendly, Visual Basic 6.0 program to implement voltage linear back projection in order to reconstruct the image by comparing the result between both projections. Through this project, the comparison result of both projections can be obtained.
