Keywords:

liquid crystals,differential interference,twisted nematic,lateral shear

Unique lateral shearing properties between ordinary and extraordinary rays appearing in twisted nematic liquid crystal cells are investigated. The small lateral shear is useful for differential interference contrast imaging systems, and a potential of electrically tuning of shear distance and/or bias retardation is demonstrated to optimize the imaging.
