OPTICAL RADIATION MODULATOR Russian patent published in 1997 - IPC

FIELD: data indication devices; magnetic field sensors. SUBSTANCE: optical radiation modulator has two sections of transparent sphere, on the interface boundary of which condition of full internal reflection is satisfied, and magnetic field source. Particles or fibres of magnetically hard, magnetically soft or magnetostrictive material are introduced on interface boundary of media sections or in close vicinity of it to create mechanical stresses under the effect of magnetic field. Two sections of transparent media may be made as fibre light guide. EFFECT: improved indication process. 2 cl, 2 dwg
