Abstract: A device, in which light waves are directed to the surface of a periodic structure constituted of a material having high reflectivity of the light wave used, whereby a field having a periodic strength of an electric field vector of the light wave is generated in the vicinity of the surface of said periodic structure, and the energy of the light wave is supplied to the charged particles while said charged particles pass through said field, thereby accelerating the charged particles.

Abstract: A light spatial modulator typically used with computer holography for modulating incident laser light with respect to two factors of three characteristic factors of a light wave, that is, the amplitude, the phase and the direction of polarization, said modulator consisting of two component modulator means tandemly disposed with respect to the incident light, each for one factor of the light wave to be modulated and each component modulator means including a plate of ferroelectric crystal such as gadolinium molybdate, the polarization of which is changed by application of a voltage.
