Abstract

Design and implementation of hardware and software has been made to gather the projection data in process of optical tomography (OT) system. This systan use the a pairs of diode laser as parallel light beam source and photodiode as detector. A test sample (phantom) is placed between it. The process of projection data is mechanically acquired by translating and rotating of test sample. Both the mechanical process are controlled by computer. The data collected by detector at different
angles are the value of light intensity attenuation after pass through the test sample. A set of data obtained show the a numbers of one dimensional projection profile of test sample at a certain angle. The collection of all projection data is called sinogram. Furthermore the cross sectional image of test sample is obtained by sinogram reconstructing. In this paper, the process image reconstruction use the iradon function in MATLAB command. The results obtained show that the system is able to gather the projection data as in standard of computed tomography.
