Real-time resonant holography using bacteriorhodopsin thin films.
We demonstrate real-time, two-dimensional measurement of species concentration in a turbulent flow field. The dynamics of pulsed holographic recording and decay are characterized for a 46-microm polymer film containing bacteriorhodopsin. We produced species-specific holographic interferograms of sodium vapor by simultaneously recording two holograms at different wavelengths, one tuned near a sodium absorption feature and the other tuned off resonance. An analysis of the techniques' sensitivity is presented.
