    摘要： An optical storage medium constitutes a substrate imprinted with optically detectable pits, each of the pits having one of a set of predetermined pit depths, each of the pits representing a number of binary bits corresponding to the number of the predetermined pit depths in the set. The pit depth is sensed unambiguously with a conoscopic holography sensor by changing the polarization of a polarized reflected beam in accordance with its angle of propagation and sensing an intensity pattern produced after the reflected beam passes through a polarized analyzer. Alternatively, using a confocal microscopy sensor, light from either the deepest or most shallow pit depth is focused on a small pin hole in an opaque surface, and a single detector measures the light intensity on the other side of the pin hole, the light intensity being a direct measure of the pit depth. The capacity of an optical memory such as a CD disk player is increased as much as four or five times by pit-depth encoding the disk, so that each pit location represent a number of bits. For example, a standard pit depth of 3 micrometers in a CD disk is divided into 0.1 micron steps so that each pit represents nearly 5 bits, providing a nearly five-fold increase in disk capacity.

    摘要： A method for producing true three dimension imagery includes positioning an object to be imaged and directing imaging laser beams to impinge upon the object. Splitting the imaging laser beams after the imaging laser beams have impinged upon the object is then accomplished, while redirecting the split imaging beams to a recording substrate.

    摘要： A hologram is recorded on a recording medium with polarized, monochromatic and incoherent light by passing the light from image points through an anisotropic medium and a polarization analyzer. A difference in phase retardation occurs for each of orthogonally polarized ordinary and extraordinary light waves which set up a transfer function of diffraction pattern at the film for recordation. The image can be reconstructed with monochromatic light passed back through the recording system, or with coherent light by illuminating the film directly to form the image on the opposite side at a position in space corresponding to the original point of the image recorded.
