If the original images are a photographic stereo pair, they undergo scanning and digitization. Digital image pairs obtained by computer graphics, computer-aided design or data visualization are used directly. The images are adjusted and registered stereoscopically in Adobe Photoshop. Lamination to a reflective aluminum-coated paper backing converts the image to a reflection print. Stereoscopic imaging applications under investigation include medical imaging, molecular modeling, underwater photography, light and electron microscopy, computer graphics, and geology.
Research continues on dyes, media, and viewing methods.
The concept of using polarizing images for stereoscopy was first described in 1940 by E.H. Land. 3 Land and his associates at Polaroid Corporation developed photographic and halftone printing processes for producing such images, which they termed Vectographs. The StereoJet process advances stereoscopy with polarizing images by using inkjet printing technology, new materials, and modern digital imaging. 3-D Prints and Transparencies, J. Imaging Sci.
