ABSTRACT:
The invention relates to the production of three dimensional images for direct viewing or for recording on a sensitized recording surface. The invention provides a method and apparatus for the direct production of integral parallax orthoscopic panoramagramic images, which objective is met by a process comprising directing at an object a means of gathering and focussing incoming radiation from the object of a wavelength to which said means is suited, positioning to either side of said gathering and focussing means a grouping means for producing a number of groups of individual waves, each group emanating from a part of said object, said grouping means generating an image in pseudoscopic form, and a means of encoding the pseudoscopic image as discrete parallactic information on a single plane, for subsequent viewing as an orthoscopic image.
