ABSTRACT:
A Christiansen cell is formed using a dispersion of two immiscible condensed phases having different optical dispersion curves, but with matching refractive indices in the vicinity of the visible spectrum. The refractive index of one phase is imagewise changed by photopolymerization, photoreduction or other photochemical reaction, or by physical means such as heat, so that the cell will transmit unscattered and scattered light components. The scattered and unscattered components can be separated by spatial filtering, and imaged to form colored images.
