ABSTRACT:
The invention discloses that a photograph with a 3-dimensional image results when the non-angular reflector (of mercury) used in the Lippmann process of color photography is replaced by an angular reflector; the preferred form of the angular reflector is a retro-reflector.
A photographic system is described which produces photographs with 3-dimensional images. The photo-sensitive element records the interference patterns of light waves, and the system is an improvement over the Lippmann process of color photography which produces photographs with 2-dimensional images. A photographic system is also described that produces a photograph with a 3-dimensional image from 2-dimensional cross sections of a subject; the system is useful in medical imaging. During exposure, motion of more than one wavelength of light is permissible between the subject and lens or the lens and the photo-sensitive element.
These improvements result from the use of a particular type of angular reflector which is a retro-reflecting sheet. This sheet is used in place of the non-angular reflector (of liquid mercury) used in the Lippmann process. The retro-reflecting sheet is covered with small sub-reflectors that are in the form of cube corners; there are 47,000 cube corners per square inch.
Improved angular reflectors are described. A diffraction grating is one of them. A way of reducing the speckle produced by a laser illuminated subject is described by the use of a moving diffuser. A transparent thermoplastic, water soluble glue is described that has a refractive index of about 1.5 and it softens at less than 200 degrees F.
