摘要:
An apparatus and method of classifying and sorting by shape crystalline objects such as synthetic diamonds in which an image of the object taken from an angle defined in relation to the object is compared to one or more templates in order to characterize the object.
摘要:
A data storage device including: a plastic substrate having a plurality of volumes (4510, 4520) arranged in tracks along a plurality of vertically stacked, laterally extending layers (4110) therein; and, a plurality of micro-holograms (4202, 4204) each contained in a corresponding one of the volumes; herein, the presence or absence of a micro-hologram in each of the volumes is indicative of a corresponding portion of data stored.
摘要:
A system (30, 50, 70, 100, 200) and method (60, 90) for replicating optical data storage discs (22, 220) (e.g., holographic data storage discs) having multiple layers of data (12). Master discs (10, 210) providing for respective single layers of data (12) are utilized, and each respective single layer of data (12) from the master discs (10, 210) are replicated onto the optical data storage disc (22, 220).
摘要:
Techniques are provided for increasing storage capacity in a holographic storage system. While typical holographic storage systems involve binary storage for each data position in a holographic disk, present techniques involve storing data such that more than two data levels may be recorded at different positions (66,68,70) in a data layer (60). In some embodiments, a recording beam directed to the disk may be adjusted to different power levels depending on the data level to be recorded. Furthermore, the recording time at a data position may be adjusted to increase the energy directed to the data position by increasing the amount of time the recording beam is impinged on the data position. Embodiments are suitable for different types of holographic storage, including dye-based medium.
