A product, method, and apparatus are provided for making a stereoscopic hologram from a series of two-dimensional views of an object. The two-dimensional views are obtained from, for example, computer analysis of scans taken by standard medical diagnostic equipment. The views are reproduced on an LCD screen, and the screen then serves as the modulator of the holographic object beam. An exposure of each view is sequentially made on a different section of a holographic recording medium, which may be, for example, a photopolymer placed on a substrate. As the observer views the finished product, each eye looks at a different section of the hologram, thus providing a stereoscopic effect. |

DETAILED DESCRIPTION The invention solves the problem of how to provide continuous structure information with respect to an object or a part of the human body in a form that is easily storable in conventional files, is easily transported, substantially eliminates the need for having specialized equipment for viewing, and achieves the above without excessive costs.
More particularly, this is achieved by providing raw image information to a computer which processes this information into a three-dimensional image, which may be encoded into any one of a number of existing formats for three-dimensional image data, either in the form of a rastorization or otherwise.
The raw image information may also advantageously be sent to an image generator, which then sends the data to the computer.
It should be noted that the images are preferably from medical scans of the human body, but need not necessarily be so.
The technology of the present invention encompasses manufacturing a hologram from any object as long as separate two-dimensional images of differing views of that object may be displayed on a screen.
Other possible objects may include architectural works or other designs.
In fact, current computer-assisted design systems make the depiction of differing two-dimensional views of these objects very convenient.
As such, they may be well-utilized by the current invention.
If a medical scan is used, it may be from, e.
g.
, an x-ray, a CAT scan, a PET scan, an MRI scan, an ultrasonic scan, and so on.
In this case, the object imaged is likely an organ of the human body.
A plurality of "views" of the three-dimensional information are then generated for the three-dimensional image data.
Each of the views corresponds to one of a sequence of views from adjacent points of view.
These points of view can be at the same distance from the image or at a varying distance therefrom.
Typically, the points of view represent the views from a series of points on a path of movement of a viewer along a line of observation, with each point being a distance from the other point to provide at least marginally discernable differences between the views from adjacent points
