  • Patent number: 7738047
    Abstract: Under one aspect, a phase contrast imaging system includes a coherent light source emitting a coherent beam directed toward a sample area; a lens arranged to collect at least part of the beam from the sample area; an element Fourier transforming the collected beam in a Fourier plane; a liquid crystal cell in the Fourier plane that transmits at least part of the transformed beam, wherein the cell includes liquid crystal molecules having a phase transition temperature, and wherein at temperatures exceeding the phase transition temperature, light transmitted through the liquid crystal molecules obtains a different phase than light transmitted through the liquid crystal molecules obtains at temperatures below the phase transition temperature; and an element inversely Fourier transforming the transmitted beam to provide an image. Part of the transformed beam has an intensity sufficient to heat a portion of the liquid crystal molecules above the phase transition temperature.
