Abstract:
A method for relaying a three-dimensional view of an object field to an observer comprising:spacing a first and a second viewpoint so that a line joining the viewpoints subtends a first angle at an object point within the object field, the first angle lying within a range of three degrees to sixteen degrees; acquiring a first image of the object field from the first viewpoint and a second image of the object field from the second viewpoint; simultaneously displaying at a plane a first relayed image of the object field acquired from the first viewpoint for viewing by the left eye of the observer and, co-located at the plane, a second relayed image of the object field acquired from the second viewpoint for viewing by the right eye of the observer; and positioning the plane at a distance from the observer so that, in use, a line joining the two eyes of the observer subtends a second angle at a point on the plane which lies in the range of three degrees to sixteen degrees.
