OPTOACOUSTIC ANALYSER OF ECOLOGICAL STATE OF ENVIRONMENT

摘要

FIELD: ecology.;SUBSTANCE: optoacoustic analyser of ecological state of the environment comprises a pulse-modulated laser, the outlet window of which is directed towards the test sample, and the acoustic piezoreceivers recording the acoustic signals, at that it is provided with an optoacoustic cell consisting of the inlet and the outlet prisms, between which a cuvette is formed for the test sample of the environment, and on the outer surface of the outlet prism two acoustic piezoreceivers are mounted, one of which is located on the axis of the line drawn through the centre of the irradiated area perpendicular to the axis of the laser, and the second is located at an angle of 50-80 degrees to this axis.;EFFECT: provision of possibility to detect heterogeneous inclusions in the liquid due to different thermal and physical characteristics of their microheterogeneities.;1 dwg
