A SYSTEM FOR ACQUIRING AN IMAGE OF A MULTI-PHASE FLUID BY MEASURING BACKSCATTERED LIGHT

摘要

An in-situ imaging system suitable for analyzing particles or droplets contained in process reactor vessels or pipelines at full process concentrations is disclosed. The system includes a light source (45) capable of high peak power output operated in a pulsed mode that is located inside of a probe. The light from the light source (45) is coupled into an optical fiber (6). The light is carried by the optical fiber to a lens system (3) near the end of the probe which focuses the light through a window (11) to an area which coincides with the field of view in the focal plane of the imaging optics (7). The imaging optics collect the light which is backscattered from particles or droplets, magnifying the image and projecting it onto an image detector (52) such as a CCD array.
