JULY 17--Stereoscopic Image System Ltd. (SIS; East Wellow, UK; www.stereoimagesystems.co.uk) and Sira Electro-Optical Ltd. (Chislehurst, Kent, UK; www.siraeo.co.uk) have signed a technology license that will allow Sira to use the SIS System in the defense and industrial markets. The SIS System enables existing single cameras and monitors to capture and display stereoscopic images without electronic modification. The captured 3-D images can be used in metrology to determine both range and relative size.

The system captures the left and right eye views in landscape format. These views are rotated through 90° and recorded as a single image. The stereoscopic images are displayed using rear and forward projection, CRT and LCD monitors, head-mounted displays, and directly on a computer.

The patented optical manipulation means that every captured scan and frame contributes to both images, therefore dramatically improving the perceived resolution of a conventional still or moving picture. It is compatible with film, analog, and digital systems. There are no electronic or physical modifications to the TV, monitor, camera, or projector. SIS's main interest is developing the base technology and welcoming inquiries from manufacturers to license the patents for their own use.
