4C-1 Adaptive Acousto-Optical Spectrometric Systems (Invited)

Some advances in AOTF-based spectroscopy are described. Adaptable spectrometers using random-spectral-access devices are presented, and it is analyzed an advantage factor, which characterizes time saving in comparison with a scanning instrument. It is presented a self-optimizing (adaptive) algorithm of spectral monitoring, which provides permanent variation of parameters of measurement procedure with use of incoming spectral information. The algorithm is implemented in differential optical absorption spectroscopy on base of specialized gas-analytic AOTF spectrophotometer. Potentials of the technique in early photoluminescence diagnostics of cancer are considered
