Complexities of image formation through liquid crystal televisions

Research output: Contribution to journalConference articlepeer-review


Liquid crystal TVs and other modulators can be expected to introduce spatial polarization variation into the wavefront and point spread function. The undesired polarization effects take the form of pixel to pixel variations of the retardance of the modulator, as well as polarization variations within each pixel. The depolarization is due to the bulk scattering in the liquid crystal, as well as possibly edge effects of the pixels. Polarization generalizations of the PSF, MTF, wavefront aberration function and similar imaging measures are necessary to characterize LCTVs and related devices. Incorporating such effects into optical design may well be a challenging endeavor.
