Device for opto-electronic detection using optical amplification, its application to telemetry and deviation measurement.

摘要

The invention relates to an opto-electronic detection device furthermore comprising, in addition to an objective (lens) (A) collecting a wave to be detected and means (E) for opto-electronic conversion, a fibre-optic waveguide (foij) in which non-linear optical effects take place. In a preferred variant, each optical fibre is doped with one or more rare earth ions, such as Erbium: Er<3+>, excited by optical pumping (D). Application to telemetry, deviation measurement and more generally to optical monitoring hardened against optical attack (counter-measures). <IMAGE>
