Resonant Holographic Interferometry, An Innovative Technique for Combustion Diagnostics.

Abstract

During this program MetroLaser pioneered the development of Resonant Holographic Interferometry (RH'); a holographic technique capable of recording the concentration of a target species in complex flame environments. Some of the attributes that make RH' attractive to the combustion community are: (1) Operates on ground state transitions (insensitive to quenching); (2) Simultaneous imaging of gaseous species and solid or liquid object; and (3) Background free signals. The program targeted the concentration measurement of species with resonant transitions in the visible (Na), ultraviolet (OH), and near infrared (K) spectral regions. This broad operating range required the development of auxiliary technologies such as real-time holographic recording and reconstruction using nonlinear optical materials. (MM)
