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.
