ABSTRACT:
This specification discloses a light modulating device comprising a liquid medium whose physical properties are variable by heat, and a heat-generating element for heating the liquid medium to such a degree that boiling does not occur to the liquid medium. The specification also discloses a light modulation apparatus comprising a liquid medium whose physical properties are variable by heat, a heat-generating element for heating the liquid medium to such a degree that boiling does not occur to the liquid medium, and a optical system for taking out one of a light flux modulated by the variation in physical properties of the liquid medium and a light flux not modulated by said variation from a state in which the light fluxes are mixedly present.
