Abstract

An optical device for modulation of the intensity of unpolarized light was constructed. In comparison with other modulators, this apparatus allows to reduce the loses of energy of light and preserve its angular divergence. The switching time and contrast ratio of the modulator are 50microsecond(s) and 300, respectively.
