RESEARCH PRODUCT

Time response of the vision binocularity by use of dynamic suppression of retinal images

subject

description

We present a novel technique for determination the stereopsis dynamic response, using as stimulus a random dot stereopair. Stereopsis can be evoked or depressed by continuous or flash illumination of the stimulus with simultaneous control of a special light scattering obstacle build in the visual path of one eye. The obstacle--a thin plate of electrooptical PLZT ceramics-- exposes (by applying of the voltage to semitransparent gold electrodes deposited on both surfaces of the plate) light scattering so blurring the retinal image, similar as for an eye with a cataract, depressing stereopsis. The random dot stereopair contains contours of images with a different stereodisparity. The PLZT plates active (covered with electrodes and light scattering) part influences a part of the image of one eye so ensuring the continuous fusion of both eye stimuli and supplying a reference stereoimage in the clear range of the stimulus.
