Abstract

The authors describe a system for the multidimensional display and analysis of tomographic images using variable focal (varifocal) length optics. The display system uses a vibrating mirror in the form of an aluminized membrane stretched over a loudspeaker; this mirror is combined with a cathode ray tube (CRT) display monitor suspended face down over the mirror, and with the associated digital hardware to generate a space filling display. The mirror is made to vibrate back and forth, as a spherical cap, by exciting the loudspeaker with a 30-Hz sine wave. 'Stacks' of 2-D tomographic images are displayed, one image at a time, on the CRT in synchrony with the mirror motion. Because of the changing focal length of the mirror and the integrating nature of the human eye-brain combination, the time sequence of 2-D images displayed on the CRT face appears as a 3-D image in the mirror.
