Abstract: A projection lens includes: first to fifth lenses; a light shielding ring; an aperture stop; and a lens barrel. The light shielding ring is rotated in a circumferential direction of the lens barrel by a rotation mechanism. In a case where an image forming panel is shifted with respect to an optical axis of the projection lens, a part, through which the light passes, is biased in the projection lens, whereby temperature distribution occurs in the lens barrel in the direction perpendicular to the optical axis. The thermal deformation of the high temperature side of the lens barrel due to the temperature distribution is greater than that on the low temperature side. The respective lenses may be tilted due to thermal deformation. By rotating the light shielding ring through the rotation mechanism, the temperature increases uniformly in the circumferential direction of the light shielding ring.

Abstract: A method and system for improving the contrast ratio of a projected image. An asymmetric aperture stop improves the contrast ratio of a projected image. Using slightly offset projection, the majority of the on-state projection light from the modulator array passes through a region that is not centered in the projection lens pupil. The blocked region of the asymmetric aperture is oriented toward the illumination path and away from the specular reflection path. The asymmetric aperture is able to block a significant portion of the diffracted light using the blocked region, without blocking much of the desired projection light passing through the remainder of the aperture. The result is that dark regions of the image become significantly darker, while light regions remain about the same. The same effect occurs without offset illumination.

The image material assembly is supported rotatably and detachably by the support body so that it can change from the image material assembly attached in the kaleidoscope body to a different image material assembly.

Abstract: A display system, of the type used by exhibitors to attract attention or to create a desired background, is characterized by new and striking visual effects. The system receives projected images upon a mobile formed of a plurality of suspended panels free to move relative to one another in air currents. The panels, when aligned, form a surface, e.g., a rectangle having a format matching the image. Images are projected onto the moving panels of the mobile with a slide projector, film projector, or other image projection means. The projected image is separated into components by the moving panels and periodically the components coalesce partly or wholly when adjacent panels move into alignment. Changes in focus and distortions of linearity occur as panels rotate in relation to the projector's field of image. Striking and dramatic visual effects result. A still photograph may be converted into a moving, dynamic image, with devices that are durable and require little attention in use.
