Title:
FULL CIRCUMFERENTIAL SPHERICAL SURFACE SCREEN PROJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2000/010055
Kind Code:
A1
Abstract:
A full circumferential spherical surface screen projection device comprising a projector (3) for projecting a projection light toward the inside of a spherical surface screen (2), a first reflection mirror (4) disposed on the optical axis (15) of the projector (3) and inside the spherical surface screen (2) and a second reflection mirror (5), a convex mirror, disposed in the vicinity of the barrel (16) of the projector (3) and on the optical axis (15), wherein a projection light from the projector (3) is projected over the full circumferential surface of the spherical surface screen (2) via the first reflection mirror (4) and the second reflection mirror (5), thereby making it possible to project an image which is full of reality over the full circumferential surface of the spherical screen by a simple structure consisting of one projector.
