Orphan date February 2009 OpticalRFID aka OPID is an alternative to RFID that is based on optical readers. Applications for opticalRFID tags may be found in future supply chain scenarios. The main advantage in comparison to traditional RFID tags is their low price and the usually employed offline preaggregation of data to the class level. Unlike most other RFID chips which use radio frequencies of 0.125 0.1342, 0.140 0.1485, 13.56, and 868 928 MHz , opticalRFID operates in the electromagnetic spectrum between the frequency frequencies of 333 Hertz SI multiples THz 3.33× 10 sup 14 sup hertz , 900 nanometer nm and 380 THz 788 nm and 750 THz 400 nm . The tag information is communicated to the reader by reflecting the read request. Parts of the incoming signal are filtered by the tag in a well defined way as it is sent back to the reader. On the reader s side, the tag data can be deduced by analysing the pattern used for filtering. ref cite web author Imagineering year 2007 title Optically Powered RFID Tags and Optical Tag Readers url http www.imagineeringezine.com e zine OPID.html accessdate 2009 03 27 ref As an alternative to reflection mode, active circuits can be used, replacing awkward RFID antennae with photovoltaic components and IR LED s on the ICs.

Multiple issues wikify July 2010 cleanup July 2010 orphan July 2010 RFID on metal abbreviated to ROM refers to radio frequency identification RFID tags which perform a specific function when attached to metal objects. The ROM tags overcome some of the problems traditional RFID tags suffer when near metal, such as detuning and reflecting of the RFID signal, which can cause poor tag read range, phantom reads, or no read signal at all. The RFID on metal tags are designed to compensate for the effects of metal. There are several tag design methods to create ROM tags. The original method was to provide a spacer to shield the tag Antenna radio antenna from the metal, creating bigger tags. New techniques focus on specialized antenna design that utilizes the metal interference and signal reflection for longer read range than similar sized tags attached to non metal objects. ref Drew Nathanson, Tom Wimmer, 2009 RFID transponders, Inlays, IC s, ITU T Lighthouse Technical Paper.

Optical engineering is the field of study that focuses on applications of optics . Optical engineers design components of optical instrument s such as lens optics lenses , microscope s, telescope s, and other equipment that utilizes the properties of light . Other devices include optical sensors and measurement systems, laser s, fiber optic communication systems, optical disc systems e.g. CD , DVD , etc. Because optical engineers want to design and build devices that make light do something useful, they must understand and apply the science of optics in substantial detail, in order to know what is physically possible to achieve physics and chemistry . However, they also must know what is practical in terms of available technology, materials, costs, design methods, etc. As with other fields of engineering, computer s are important to many perhaps most optical engineers. They are used with instruments, for simulation, in design, and for many other applications. Engineers often use general computer tools such as spreadsheet s and programming language s, and they make frequent use of specialized optical software designed specifically for their field. Optical engineering metrology uses optical methods to measure micro vibrations with instruments like the laser speckle interferometer or to measure the properties of the various masses with instruments measuring refraction .

Unreferenced stub auto yes date December 2009 File Optical Circulator symbol.jpg thumb Optical Circulator symbol An optical circulator is a special optical fiber fiber optic component that can be used to separate optical signals that travel in opposite directions in an optical fiber , analogous to the operation of an electronic circulator . An optical circulator is a three port device designed such that light entering any port exits from the next. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1, but instead exits from port 3. Circulators can be used to achieve bi directional transmission over a single fiber. Because of its high optical isolator isolation of the input and reflected optical powers and its low insertion loss , optical circulators are widely used in advanced fiber optic communications communication systems and fiber optic sensor applications. Optical circulators are non reciprocal optics, which means that changes in the properties of light passing through the device are not reversed when the light passes through in the opposite direction. This can only happen when the symmetry of the system is broken, for example by an external magnetic field . A Faraday rotator is another example of a non reciprocal optical device.

Image Optical Interleaver.gif thumb 400px right Illustration of the function of an optical interleaver and de interleaver An optical interleaver is a 3 port passive fiber optics fiber optic device that is used to combine two sets of dense wavelength division multiplexing DWDM channels odd and even channels into a composite signal stream in an interleaving way. For example, optical interleaver takes two multiplexed signals with 100 GHz spacing and interleaves them, creating a denser DWDM signal with channels spaced 50 GHz apart. The process can be repeated, creating even denser composite signals with 25 GHz or 12.5 GHz spacing. The device can be used in a reverse direction, forming an optical deinterleaver that separates a denser DWDM signal into odd channels and even channels. See schematic diagram. For example, in most DWDM equipment, the standard channel spacing is 100 GHz. But spacing the signal carrying frequencies every 50 or even 25 GHz can double or even quadruple the number of channels per fiber. Thus, optical interleaver can expand the number of channels per fiber, and devices and or networks can be upgraded without requiring that all devices be upgraded. Optical interleaver is based on multiple beam interference . Currently, there are two approaches to building optical interleaver 1 Step phase Michelson interferometer , and 2 birefringence Birefringent crystal networks. The former is based on Michelson interferometer combined with Gires Tournois interferometer .

There are currently 155 locations in the United States, Canada , and the U.S. Virgin Islands . History Sterling Optical opened in 1912 with a single store in the financial district of New York City . In 1954, a second location opened in Washington, D.C. In 1966, Sterling Optical acquired IPCO, a retail optical chain in the northeastern United States. The chain grew to 20 stores by 1970 and to 65 by 1975. Over the next 5 years, the chain grew to almost 130 stores. In January 1992, Sterling Optical was incorporated in New York as a result of a reorganization and was renamed Sterling Vision Inc., with stores doing business as Sterling Optical.
