Optical tomography system using microprocessor and ethernet

Abstract

Purpose: Owing to the high cost of data acquisition (DAQ) card in the market, the purpose of this paper is to develop a high speed, low-cost microprocessor and ethernet controller-based DAQ in optical tomography system. Design/methodology/approach: Microprocessor is the main core to control the sensor circuitry while ethernet controller has the responsibility of transmitting data to PC and thus insuring the reliability of data. Findings: The data transfer rate will be up to megabytes per seconds. In this optical tomography system, projection geometry combining two orthogonal and two rectilinear in one layer is modeled. Originality/value: This paper presents a new application in optical tomography.
