However, advancements in silicon fabrication technology allow nowadays the fabrication of powerful Digital Signal Processors (DSP) at a reasonable cost. This allows this technology to be used in an optical tomography system since data acquisition and processing can be performed within the DSP. Thus, the dependency on a personal computer and a DAQ to sample and process the external signals can be reduced or even eliminated. The DSP system was customized to control the data acquisition process of 16×16 optical sensor array, arranged in parallel beam projection. The data collected was used to reconstruct the cross sectional image of the pipeline conveyor. For image display purposes, the reconstructed image was sent to a personal computer via serial communication. This allows the use of a laptop to display the tomogram image besides performing any other offline analysis. 2009-08-18T04:12:59Z 2009-08-18T04:12:59Z 2008-03 Article Sensors, vol.8 (4), 2008, pages 2082-2103. 1424-8220 http://www.mdpi.com/1424-8220/8/4/2082 http://hdl.handle.net/123456789/6979 en Molecular Diversity Preservation International (MDPI) |
