Abstract

A new and improved compact disc case apparatus includes a lower case assembly and an upper case assembly which are placed in registration with each other to form an enclosure assembly. The enclosure assembly includes a side which contains a slot. A pivot assembly is connected between the lower case assembly and the upper case assembly adjacent to a first lower corner and a first upper corner. A disc retention tray is positioned between the lower case assembly and the upper case assembly. The disc retention tray pivots on the pivot assembly such that the disc retention tray can be selectively moved to an open position or a closed position. In the closed position, the disc retention tray is housed completely in the enclosure assembly. In the open position, the disc retention tray is substantially outside the enclosure assembly such that a disc can be selectively taken off of and placed on the disc retention tray. The disc retention tray includes a handle portion.

Abstract

The present invention is a holographic structured light generator (HSLG) for generating an array of an arbitrary number of laser beamlets from a single laser beam using a point laser light source and a hologram. In a first preferred embodiment of the present invention, a hologram having an image of four point sources in a common plane is fabricated using four point sources as the object beam, and a reference beam. A reconstruction beam, aligned identically with respect to the hologram as was the reference beam during fabrication of the hologram, is then directed at the hologram, generating the array of laser beamlets from the four point sources in the hologram. In a primary application of the HSLG, it is used to map the surface of an object in three dimensions. The HSLG is used with video cameras, computer image processing equipment and an optical spatial light modulator to yield 3-D data for use with CAD systems.
