CORRELATIVE-EXTREME MODE OF REMOTE MONITORING POLLUTED SUBSTANCES Russian patent published in 2007 - IPC G01N21/39 

FIELD: the invention refers to the field of investigation or analysis of substances with the aid of optical means namely to remote monitoring and identification of polluted substances at surveying with using multi-frequencies sources of coherent electric magnetic radiation of optical diapason.

SUBSTANCE: the mode is in single-multiple scanning of the echo signal in the whole chosen for indication frequency diapason of generation of laser radiation with following correlative-extreme analysis of the registered spectrum. The identification of substances is executed on maximum values of the coefficients of correlation of the echo-signal calculated on multiple model spectrums received in statistic conditions of measuring.

EFFECT: allows increase of quick action of optical location systems and specification of detecting the given list of polluted substances.
