electromagnetic deflection
1. The use of a magnetic field or external horizontal-deflection and vertical-deflection coils to deflect an electron beam in a television picture tube or an oscilloscope.
2. Deflection of an electron stream by means of a magnetic field.

In a television picture tube, the magnetic fields for horizontal and vertical deflection of the electron beam are produced by sending sawtooth currents through coils in a deflection yoke which goes around the neck of the picture tube.

electro-optic deflection
The effect whereby a light beam is deflected by a birefringent prism when its polarization is changed by voltage applied to an electro-optical crystal through which the beam passes.

The deflection of the beam depends on its particular polarization.

electrostatic deflection
1. The deflection or the displacement of an electron beam from its straight-line path of an electron beam by means of an electrostatic field which is produced by electrodes on opposite sides of a beam. 2. A technique for modifying the path of a stream of charged particles by the use of an electric field applied across from side to side or at right angles to the path of the particles.
3. The movement of an electron beam as a result of the electrostatic field produced by electrodes on either side of the beam.

It is primarily used in cathode-ray tubes for oscilloscopes and in old-fashioned television picture tubes.

The electron beam is bent toward a positive electrode and bent away from a negative electrode or it is attracted to a positive electrode and repelled by the negative electrostatic charges.
