Abstract

An adjustable, head mountable stereoscopic viewer having a head band to mount the viewer to the user. A tilt bracket is pivotally joined on one end to the head band and at a pivot point on an opposite end to an optical assembly for adjustment of the assembly position to obtain maximum field of view. The optical assembly includes first (left) and second (right) mirror assemblies that receive and direct left and right stereo images from an image source, such as a poster, a TV image, etc., to the corresponding left and right eyes of the user. The left and right stereo images are displayed horizontally at the source, the right image preferably displayed above the left image. Each mirror assembly has two mirrors and an aperture, and functions in a similar manner to a periscope. Adjustment for a range of image sizes and distances is accomplished with a mirror adjustment, provided to vary the tilt of the mirror of one of the assemblies to adjust the overlap of the images. The optical assembly is adjustable about the pivot point to eliminate the unwanted upper (right) image from the left eye. An adjustable shutter plate is provided to restrict the optical opening to the right assembly for eliminating the unwanted lower (left) image from the right eye.
