Abstract
A light-modulating cell for providing a desired propagation of light impinging thereon is presented. The cell comprises at least two substrates, made a material substantially optically transparent with respect to incident radiation of a desired wavelength range, and at least one reservoir attached to at least one of the substrates. These at least two substrates define a plurality of spaced-apart outer surfaces and a sealed therebetween, respectively. The space is filled with a first, substantially liquid light-modulating medium, while the reservoir contains predetermined amount of a second, substantially liquid light-modulating medium. The inside of the reservoir is connected to the inside of the sealed space for providing a continuous flow of the first and second media into and out of the space.
