Storage medium for optical data and optical data disc A storage medium for optical data according to the invention comprises a substrate (S) and an active layer (A).

The path side data may be optical data or optical data modified based on one or more panoramic images.

A method of optical sensing comprising generating optical data associated with an object of interest, generating non-optical data associated with the object of interest, and analyzing the optical and non-optical data.

The photochromic material of the present invention is useful as an optical data storage carrier, a fraud-proof optical data carrier, security ink, and in other optical applications.

A computer system has an optical data distributing device for transmitting and distributing optical signals.

The optical bit rate converter converts an ultra-high speed optical data stream to a lower rate optical data stream.

Accordingly, an optical data loss rate can be reduced such that optical data can be efficiently transferred.

The egress edge units (160) receive the super packets, de-aggregate the super packets into the original optical data packets, and transmit the optical data packets to the data lines (20).

In accordance with the invention, respective optical receivers convert the optical data signals to respective electrical data signals, which a TDM data multiplexer time-multiplexes to generate a multiplexed data signal.

Optical data traffic is conducted between nodes via a fiber link.

Some embodiments include comparing, using a processing unit, optical data with magnetic data to determine whether optical data corresponds with magnetic data.

Methods of performing complex optical computations, preferably using a programmable optical data processor.

An optical image represented by optical data is obtained by an optical sensor and processed in order to improve the stochasticity of the optical data.

The 'added' optical data streams may be added to the outgoing optical fiber(s) at any unused wavelengths, including, but not limited to, the wavelengths of the 'dropped' optical data streams.

Data sensors would then be provided by optical data sensors.
