Magneto optical deflector |
摘要 |
The invention concerns the magneto-optical deflectors which enable an incident beam of radiant energy to be deflected in a variable manner under the control of a magnetic field. It consists in using a thin film of a magnetic material forming a diffraction grating, means for travelling the incident beam along the plane of this thin film, and means for magnetically controlling the step-width of the grating, thus controlling the angle of deflection given by this grating.
