To address the Armyâs need for compact, robust, real-time, high-capacity holographic data storage (HDS) for test instrumentation, Physical Optics Corporation (POC) proposes to develop a new Miniature Encrypted Random Addressing Holographic Memory Cube Data Storage (MERAH) system. This proposed system is based on novel use of tunable laser diode array for recording/readout to achieve fast recording and readout speed and random addressing with virtually unbreakable encryption, an optical phase-conjugate design for system ruggedness and compactness, and multiple-page read/write technology to achieve ultra-high storage capacity (> 8 terabytes) and data transfer rate (> 2 Gbits/s). The MERAH system is a ruggedized stand-alone unit operating on 12/24 VDC power with size of < 20 cubic inches and power consumption < 20 watts. It offers standard interfaces to existing instrumentation through IEEE 1394 (Firewire) and Serial Advanced Technology Attachment (SATA) II connections and is capable of storing classified information. In Phase I, POC will demonstrate the feasibility of MERAH by investigating the system design by computer modeling, and fabricating and testing a breadboard prototype in a simulated corrosive environment. In Phase II, an advanced, miniaturized MERAH engineering prototype will be assembled and tested both at POC and at an Army facility.
