A system for portable secure viewing of an image having the added advantage of presenting true three-dimensional imagery is disclosed. In operation the system is brought to a viewing location where it is opened up, configured and activated. Upon activation, an image is provided by an image source to an image projector which projects the image through a projecting lens focusing the image upon a transmissive field lenses or reflective field screens which in turn provide the image to a pupil locations. A viewer resident at the pupil location is able to see the image projected while others cannot. After viewing is completed, the system is turned off and closed for transportation. The system can then be moved to a second location providing additional secure viewing.
