Abstract

This device provides a 3-D display of graphic computer output or plotter output. A hologram is made, by the system comprising laser 20, lens 22, mirror 24 and film 1 1, of the face of either dark trace CRT 10 or an electrostatic storage and display tube. Either tube receives the computer output and presents an image which can, for example, be part of a sectional drawing, a cross-section of a three-dimensional object, a multiaxis plot on x, y, z axes, a mathematical construct, etc. After holographing film 11 at plane 12 on the z axis, CRT 10 is moved a distance corresponding to a distance along the z axis of the actual object. A new cross-section plane 14 is displayed and another exposure made on film 11.

3 D Holograms

This device provides a 3-D display of graphic computer output or plotter output. A hologram is made, by the system comprising laser 20, lens 22, mirror 24 and film 1 1, of the face of either dark trace CRT 10 or an electrostatic storage and display tube. Either tube receives the computer output and presents an image which can, for example, be part of a sectional drawing, a cross-section of a three-dimensional object, a multiaxis plot on x, y, z axes, a mathematical construct, etc. After holographing film 11 at plane 12 on the z axis, CRT 10 is moved a distance corresponding to a distance along the z axis of the actual object. A new cross-section plane 14 is displayed and another exposure made on film 11. After multiple exposures are made at planes 12, 14, and 16, film 11 is developed and displayed as a conventional hologram. The image seen appears as a phantom drawing in three dimensions. The cross-sections displayed by the CRT 10 can be modified by the computer so that partially or completely hidden lines can be completely or partially erased so as to construct a more solid 3-D image.
