Temporal measurements in the spatial frequency spectrum of liquid crystal image transducers.
A new procedure to test and evaluate imaging properties of liquid crystal optical transducers is described. The method involves the observation of temporal histories of image-related Fourier spatial frequency signals and is demonstrated for a grating input. Results show that information on timing of spectrum events can be used to modify coherent light imagery. A comparison of spectral features for two liquid crystal transducer types is given.
