METHOD OF MEASURING POLARISATION SENSITIVITY OF OPTICAL RADIATION RECEIVER (VERSIONS)

摘要

FIELD: physics. ^ SUBSTANCE: proposed method comprises subjecting tested receiver to radiation passed through polariser and analyser. Note here that analyser is periodically revolve at preset pitch and at each pitch radiation intensity is measured. Obtained dependence of radiation intensity upon analyser orientation azimuth is used to determine amplitude of 2nd and 4th harmonic components top judge about polarisation sensitivity of receiver. In compliance with second version, 2nd harmonic signal shift is determined. ^ EFFECT: higher accuracy and degree of process automation. ^ 2 cl, 1 dwg
