Abstract

The problem of finding the optimum measurement algorithm is formulated for acousto-optical spectrometers (AOS) exhibiting random spectral access. The problem is treated with the example of the measurements of a substance abundance in a two-species mixture. The optimum algorithm depends on the noise spectral distribution and the abundance of the interfered substances. The optimization being a part of the measurement process makes available the adaptation of that process to the analyzed sample. This DOAS technique based on measurements in a few selected spectral points finds an application to UV AOS-based gas analyzers for ambient air monitoring.
