Tomographic Imaging Using Optical Sensor Arrays

Abstract

This paper describes an investigation into the use of an optical fibre sensor to measure the flow of pneumatically conveyed solid particles. The diameter of the fibre sensor is 1mm. A tomographic measuring system constructed from arrays of tran ducer pairs is described, which is capable or capturmg sufficient data and reconstruct an image flow. Two arrangement, orthogonal 8x8 and 16x16 will be discused later and comparisons of resolution made using phantoms in a pipe or 81mm diameter cross-section with a phantom.
