1. A method for controlling the haze in a holographically polymerized polymer dispersed liquid crystal optical element comprising:

  • forming a loosely gelled network within a pre-polymerized polymer dispersed liquid crystal material; and

    holographically polymerizing the polymer dispersed liquid crystal material, including the loosely gelled network, to form the polymer dispersed liquid crystal optical element with decreased haze.
