WIDE ANGLE VIEWING DEVICE

摘要

A device for wide angle viewing, comprising of goggles made of opaque material which has been installed with at least one Vector Light Source (VLS). The vector light source is a light source which emits a narrow light beam only in one pointing direction. The set of said vector light sources are divided into at least one subset. Each subset has a center location. All the vector light sources included in each said subset are pointed at the same center location of their subset. Each such subset could be made to display an image. Another kind of said viewing device enables viewing of a pair of stereoscopic images by having two subsets of vector light sources each with a center location. The two center locations can be adjusted to fit the locations of the pupils of the left and right human eyes. In order to achieve vector light sources which emit narrow light beams, each of the vector light sources is installed at an end of a tunnel opening in the goggles and the tunnel opening has a predetermined width which is narrow enough such that the tunnel opening allows the light of its vector light source to propagate only in predetermined narrow range of directions. The light sources of the vector light sources could be made from Light Emitting Diodes (LEDs) or from light sources controlled by Liquid Cristal Displays (LCD).
