Light Scattering Parameters of Polymer Dispersed Liquid Crystals Obtained by Inversion of Experimental Data

• Polymer Dispersed Liquid Crystal (PDLC) devices are electrically controlled smart windows, that switch from a translucent milky appearance (off state) to a transparent clear appearance (on state). We have studied the intrinsic and extrinsic scattering and absorption coefficients obtained by inversion of spectrophotometric transmittance and reflectance data. The inversion procedure uses two flux and four flux models and similar approximations for the average crossing parameter (ACP) as in our previous workon suspended particle devices [1]. Good fits are obtained, but the ACP approximation was found to be inconsistent with fitted parameters.
