Optical diagnostics of pressure and temperature using laser induced thermal gratings

Laser induced thermal grating spectroscopy (LITGS) is based on scattering from gratings produced by interference in a resonantly absorbing gas, of two pump laser beams crossing at a small angle. Interference between a stationary temperature grating and induced acoustic waves leads to a modulation of...
