Abstract: Three-dimensional images are produced from a sequence of images generated by a single camera mounted on a platform moving at constant velocity and spacing with respect to a subject to be imaged. Stereoscopically related images in the sequence are presented for viewing alternately at a rate of about ten per second so that the image seen by an observer is perceived as having depth. By recording the stereoscopically related images alternately on the same film, the images produced when the film is projected are perceived as three-dimensional. A video camera may be used to generate the original sequence of stereoscopically related images, in which case the images are digitized, stored, read out alternately at a rate of about ten per second and displayed to produce an image which is perceived by an observer as having depth.

Abstract: Development of a three-dimensional illusion through sequential displaying on a viewing surface of images of the subject as viewed alternatively first from one point of origin and then, time displaced, from another point of origin at a rate within a range of 4 to 30 changes between the points of origin per second. The effect of the illusion is maximized by having the points of origin vertically aligned with respect to one another and having the points of origin displaced from one another a distance less than normal interoccular distance.
