Data acquisition system for optical tomography system using advanced microprocessor

Abstract

During year 1980's, Tomography System was initiated to be used in industrial process for system monitoring. Data Acquisition System (DAS) is a core unit in Tomography System which required for obtaining accurate outputs possible in data sampling. However, there are very limited numbers of equipment in market which are able to perform data acquisition system unit for an Optical Tomography. This scenario makes DAS becomes expensive. The use of expensive DAS can be eliminated by replaced with a low cost embedded system design. This project develops a simple, cheap and portable data acquisition system for Optical Tomography System. The developed embedded system can be used to control the data acquisition of 128x64 pixels from Complementary Metal Oxide Semiconductor (CMOS) optical image sensor. The output pixels from the optical image sensor are sent and presented to Visual Basic Application display unit. The image from sensor was verified and categorized successfully
