A research group at the MIT Media Lab has reported the use of polarization field synthesis to create a dynamic light field display. The prototype display is composed of multiple LCD layers, each acting as polarization rotators, enclosed by a pair of crossed linear polarizers. A four-dimensional light-field can be emitted by algorithmically determining the optimal rotations to be applied at each layer of the display. <ref>{{cite journal|last=Lanman|first=Douglas|coauthors=Gordon Wetzstein, Matthew Hirsch, Wolfgang Heidrich, Ramesh Raskar|title=Polarization fields: dynamic light field display using multi-layer LCDs|journal=ACM Transactions on Graphics (TOG)|date=6|year=2011|month=December|volume=30|issue=6|doi=10.1145/2070781.2024220|accessdate=27 December 2011}}</ref>
