Abstract
Abstract A projector and method are disclosed for projecting 360* pictures or scenes wherein a wedge or substantially line image portion is taken substantially normally from an annular picture or projected image and directed along an optical axis which is folded through substantially 90* and projected on a spherical segment or cylindrical surface and the segment or line image is swept around the annular picture or projected image about a rotational axis coincident with that of the annulus and spaced from the optical axis by the focal length of the projecting optical system. Several image systems can be used to establish the image to be projected and one of such image systems can have its optical axis shifted from the axis of the annulus to the optical projection axis for properly shifting a runway in a projector and method used in an aircraft simulator.
