System Data

In the past, most of the researches in tomography system concentrated more on the design of the sensor, and made use of the data acquisition system as the interface to the personal computer. This will increase the cost of the system. In this project, Universal Serial Bus was successfully implemented in an optical tomography system, providing a low cost, high–speed data acquisition system. The system, however, is an offline system. The system had successfully processed all the data in the lower level, using the micro controller before sending the data into the PC through the USB. Key words: Universal Serial Bus, optical tomography system, data acquisition system, tomogram

Sensor Measurement

The main purpose of this study is to design the optical tomography system for four projections complementary metal–oxide–semiconductor (CMOS) linear image sensor. This system includes the development of suitable driver for the operation of CMOS S10077 linear image sensor, measurement section and data acquisition system. The CMOS linear image sensor S10077 is configured around a flow pipe with an octagonal–shaped measurement section. This image sensor scans image of object inside the pipe from four different projections angle. When light hit the object, shadow will cast on the sensor surface. The output signal is obtained based on the light intensity projected to the sensor. Microcontroller PIC 18F4620 is used as a driver to enable the operation of CMOS linear image sensor and microcontroller PIC 18F458 is used as a data acquisition circuit for optical tomography system. Microcontroller retrieves serial data from the CMOS linear image sensor and sends it to a PC for further work in image reconstruction.
