AI Technical Summary

Problems solved by technology

An additional disadvantage of the Infitec approach is that it has a relatively high cost compared to glasses using polarization-based 3D stereoscopic displays
The high cost of the prior art Infitec glasses is due to the high number of dielectric layers (approximately 50-100 layers) required to obtain a high stereo extinction ratio
The cost of coated glasses with interference filters is approximately proportional to the number of dielectric layers and the combined thickness of all these layers, and thus the large number of layers results in a high cost of the glasses

Embodiment Construction

[0037] figure 1 A generalized illustration of a 3D stereoscopic display system 10 is shown in . Left image data 11 and right image data 12 are input to a display unit 13 . The display unit 13 displays the left eye image data 11 and the right eye image data 12 on the same or substantially the same spatial imaging grid by wavelength division multiplexing and time division multiplexing. The goggles 14 perform wavelength selective filtering, ensuring that the left eye 15 sees the left image data 11 and the right eye 16 sees the right image data 12 .

[0038] In an embodiment of the invention, the display unit 13 is a projection display. A display unit 13 of the projection display type is shown in figure 2 middle. The stereoscopic lighting unit 101 performs wavelength division and time division multiplexing of lighting. The illumination optics 102 images the illumination onto one or more spatial light modulators 103 . Projection optics 104 images the surface of one or more s...

Abstract

This invention relates to a stereoscopic viewing aid for viewing images received from a stereoscopic imaging system, the imaging system comprising two channels providing images having two different sets of wavelength ranges, the viewing aid comprising two filtering means, the first transmitting light within the first set of wavelengths and the second transmitting light within the second set of wavelengths, each of said filtering means comprising a first optical device having a selected focal length at the corresponding wavelengths.

Description

field of invention [0001] The present invention relates generally to eyewear for use as a viewing aid for 3D stereoscopic displays, and more particularly, to eyewear for viewing wavelength division multiplexed based 3D stereoscopic displays. technical background [0002] There are several different methods for providing stereoscopic 3D images when viewing a display, such as shuttered glasses (where two images are displayed sequentially and shutters placed in the glasses that determine which image is displayed to which eye ), and polarized glasses and a projector or screen (where the glasses send only the right or left image to the respective eye). The disadvantages of shutter glasses are that they require the glasses to be active (battery required), dark (20% visible light transmission), and have a limited refresh rate. The disadvantage of polarized glasses is the need to maintain polarization in the screen, making it difficult to achieve high stereo extinction ratio and re...
