Dual Gated Imaging system for Enhanced Fluorescent Diagnostics Measurements
Abstract
This report describes the purchase specifications and initial use of a dual gated imaging system capable of intensified imaging with gate times a short as 1 nsec. The system consists of two primary subsystems: (1) dual fast gated image intensifiers, and (2) a sensitive CCD camera and readout/computer system. With dual images, it is possible to measure the fluorescent lifetimes of the dopant which is the marker for the fuel, fluoranthene, in a two dimensional image, and subsequently to correct the fuel intensity image for oxygen quenching. From the fuel and oxygen images, the equivalence ratio image can be calculated. In initial experiments, the system has been used to capture instantaneous (<50 nsec) equivalence ratio images for gaseous methane jets and for diffusion flames.
