Laser-beams or -sheets is applied as detection sources of a flow with solute or particle suspension. The concentration field is estimated inversely from the integrated information of the light intensity attenuation by means of CT-scan technology. The instrument can measure quasi-instantaneouly and quasi-continuously a 2D concentration distribution of sediment. The principle of the inverse estimation of concentration, the design of the instrument and a preliminary test result are described. This
