Modeling orthogonal and rectilinear mixed-modality projection of optical tomography for solid-particles concentration measurement

In optical tomography, light attenuation/scattering methods have been used to determine average solids concentrations in gas-solids flows. Derived from the Lambert–Beer law, the Mie theory forms the theoretical basis for optical sensor. It states that the intensity of light transmitted through a dilute gas–solids mixture should be exponentially related to the solids concentration in the light beam. In this context, the light transmits continuously and any particle passing though the volume interrogated by a sensor is detected as variation in the level of illumination of the sensor. This paper focused the modeling for a novel mixed-modality of orthogonal and rectilinear projections. A novel image reconstruction algorithm has been applied and also tested on the modeling.
