FIELD: measurement technology.
SUBSTANCE: method includes application of probing optical signals directly to specified part of space, measurement of spectrum of dissipation and excited fluorescence spectrum within preset part of area. Moments of measurement of amplitudes of spectral components of received signals are defined by distance D to area of measurement. Diagram of measured differential image is subsequently put to coincidence with closer criterion differential spectral images and better approach is found. Transmitting optical system of the device and receiving optical system are connected together through measured part of area. Optical system can be oriented at the direction of tested part of space.
EFFECT: improved speed of measurement.
