Title:
Setup and Fabrication of Cost Effective, Robust Fiber Optical Needle Probes for Application in Multiphase Flows 
Abstract:
A fiber optical probe for detection of void fraction in multiphase flows consisting of silica fibers with core diameters of 200 and 400,textmu m is presented. Using beam splitter optics with a polarizing filter and a diode laser for illumination, a robust and cost-effective sensor was developed and evaluated in two phase flows with and without phase change. The setup and manufacturing process of the components as well as the post processing of the signals are described in detail.
