FIELD: physics.
SUBSTANCE: apparatus has a generator of electromagnetic oscillations 1, connected by the output to an emitter 2, a first receiver 3, a first detector 4, a second receiver 5 connected to the input of a second detector 6 and a computer 7. Operation of the apparatus is based on conversion of electric field strength of reflected electromagnetic waves from two boundary surfaces of media.
EFFECT: high accuracy of measuring thickness of dielectric coating deposited on a dielectric base.
