İğne deliği görüntüleme temelli stereoskopik 3B ve başa takılan göstergeler için çözümler

Two well-known existing problems of stereoscopic displays are the accommodation-convergence conflict and the lack of natural blur for defocused objects. We present a new technique that we name Super Stereoscopy (SS3D) to provide a convenient solution to these problems. Regular stereoscopic glasses are replaced by SS3D glasses which deliver at least two parallax images per eye through pinholes equipped with light selective filters. The pinholes generate blur free retinal images so as to enable correct accommodation, while the delivery of multiple parallax images per eye creates an approximate blur effect for defocused objects. Experiments performed with cameras and human viewers indicate that the technique works as desired. In case two pinholes equipped with color filters per eye are used, the technique can be used on a regular stereoscopic display by only uploading a new content, without requiring any change in display hardware, driver or frame rate. Apart from some tolerable loss in display brightness and decrease in natural spatial resolution limit of eye due to pinholes, the technique is quite promising for comfortable and realistic 3D vision, especially enabling the display of close by objects that are not possible to display and comfortably view on regular 3DTV and cinema. We propose a simple virtual reality (VR) type head-worn display (HWD) system, where a pinhole array relays the image on a smart phone display to the retina of a user without requiring any lenses. The sub-images relayed through the pinholes are seamlessly tiled on the retina without ghost (double) images or blank regions by using an optimized pinhole design and by pre-processing the images shown on the cell phone. A proof-of-concept prototype with a 3 mm exit pupil successfully verifies the developed theory and demonstrates the delivery of full color images within a diagonal field-of-view (FoV) of 45 degrees at a resolution of about 4 cycles per degree. The experiments also demonstrate the interesting possibility that there are multiple options for the display content that generates a desired retinal image, including those obtained with random decisions. The system is low-weight, very low-cost, and can deliver diffraction-limited images across a wide FoV. However, the spatial resolution is moderate due to small pinhole size. Also, pupil tracker sensors and a dynamically configurable pinhole array are needed to handle changing pupil size and locations.
