Title: Laser-induced fluorescence measurements of dual plumes and comparison of laser-induced fluorescence and conductivity probe measurements
Author: Chrzan, Joseph Coleman
Abstract: The laser-induced fluorescence (LIF) technique is used to visualize and quantify the concentration field around a conductivity probe. The LIF data are compared to the signal collected by the conductivity probe. The objective is to compare the signal of the contact-sensor to the "ground-truth" measurement of the LIF data. Detailed comparison of the temporal response and the peak detection are presented. In addition, a proof-of-concept of a two-color LIF technique is presented using Rhodamine 6G paired with an Argon-ion laser and simultaneously Oxazine 725 paired with a Krypton-ion laser. Optical filters on two digital cameras isolate the emitted light from these respective laser/dye combinations. The objective is to provide detailed quantitation of two over-lapping (non-reactive)chemical plumes.
