EMISSION SOURCE WITH LOW LEVEL OF INTENSITY NOISES FOR FIBRE-OPTIC GYROSCOPE

摘要

FIELD: measurement equipment.;SUBSTANCE: device includes a source, the optic emission from the output of which is divided into several propagation channels of various length. Source output is connected to the first input of the first divider of row of N dividers. Every first output of the previous divider of the row is connected to the first input of every next divider. The second input of each divider is connected by means of a light-emitting diode with its second output. Length of each light-emitting diode is more than length of LK coherence of the source emission and more or less than length of the light-emitting diode of every next divider of that row by length of LK coherence of the source emission. Length of the light-emitting diode connecting the second input and output of the first divider of row of N dividers is more than NLK.;EFFECT: reduction of intensity noises of an optic emission source.;2 cl, 5 dwg
