This paper presents the use of charge coupled device (abbreviated as CCD) linear image sensors in an optical tomographic instrumentation system used for sizing particles. Four CCD linear image sensors are configured around an octagonal shaped measurement section for a four projections system. The system consists of lighting system, data acquisition system and image reconstruction system. The measurement system is explained and uses four CCD linear image sensors consisting of 2048 pixels with a size of 14 micron by 14 micron. Hence, a high-resolution system is produced. Image reconstruction for the four-projection optical tomography system is generated using Matlab software.
