Abstract

A retroreflective array is used in the phase conjugate configuration to compensate for refractive noise in flame atomic absorption spectroscopy. The system is shown to provide reductions in refractive noise by a factor of five to seven, using the Mn 403. 1-nm line. The compensation provides 10-50% increase in sensitivity in noisy flames.
