Opticalengineering 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. Opticalengineering 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 .

Optical physics is a subfield of atomic, molecular, and optical physics . It is the study of the generation of electromagnetic radiation , the properties of that radiation, and the interaction of that radiation with matter , especially its manipulation and control. It differs from general optics and opticalengineering in that it is focused on the discovery and application of new phenomena. There is no strong distinction, however, between optical physics, applied optics, and opticalengineering, since the devices of opticalengineering and the applications of applied optics are necessary for basic research in optical physics, and that research leads to the development of new devices and applications. Often the same people are involved in both the basic research and the applied technology development. Researchers in optical physics use and develop light sources that span the electromagnetic spectrum from microwave s to X ray s. The field includes the generation and detection of light, linear and nonlinear optics nonlinear optical processes, and spectroscopy . Laser s and laser spectroscopy have transformed optical science. Major study in optical physics is also devoted to quantum optics and Coherence physics coherence , and to femtosecond optics. In optical physics, support is also provided in areas such as the nonlinear response of isolated atoms to intense, ultra short electromagnetic ... field. Other important areas of research include the development of novel optical techniques for nano optical measurements, diffractive optics , low coherence interferometry , optical coherence tomography , and near field microscopy .

Refimprove date December 2009 Optical storage is a term from engineering referring to the storage of data on an optically readable medium. Data is recorded by making marks in a pattern that can be read back with the aid of light , usually a beam of laser light precisely focused on a spinning disc. An older example, that does not require the use of computers, is microform . There are other means of optically storing data and new methods are in development. Optical storage differs from other computer data storage data storage techniques that make use of other technologies such as magnetism or semiconductor s. Optical storage can range from a single drive reading a single CD ROM to multiple drives reading multiple discs such as an optical jukebox .

unreferenced date December 2006 In optics , optical bistability is an attribute of certain optical device s where two resonant transmissions state s are possible and stable, dependent on the input. Optical devices with a feedback mechanism , e.g. a laser , provide two methods of achieving bistability . Absorptive bistability utilizes an absorber to block light inversely dependent on the intensity of the source light. The first bistable state resides at a given intensity where no absorber is used. The second state resides at the point where the light intensity overcomes the absorber s ability to block light. Refractive bistability utilizes an optical mechanism that changes its refractive index inversely dependent on the intensity of the source light. The first bistable state resides at a given intensity where no optical mechanism is used. The second state resides at the point where a certain light intensity causes the light to resonate to the corresponding refractive index. This effect is caused by two factors Nonlinear atom field interaction Feedback effect of mirror Important cases that might be regarded are Atomic detuning Cooperating factor Cavity mistuning Applications of this phenomenon include its use in optical transmitters, memory elements and pulse shapers.

orphan date January 2010 Wikify date January 2010 The optical force is a phenomenon whereby beams of light can attract and repel each other. The force acts along an axis which is perpendicular to the light beams. Because of this, parallel beams can be induced to converge or diverge. The optical force works on a microscopic scale, and cannot currently be detected at larger scales. It was discovered by a team of Yale researches led by electrical engineer Hong Tang. ref http discovermagazine.com 2010 jan feb 083 Top 100 Stories of 2009 83 Like Magnets, Light Can Attract and Repel Itself , Discover magazine, from the January February 2010 special issue published online December 21, 2009 ref See also Optical lift References reflist DEFAULTSORT Optical force Category Force Category Spacecraft propulsion Category Aerospace engineering physics stub science stub ... more details

fields of science and engineering. In particular, the use of optical methods has been playing ...An optical dilatometer is a non contact device able to measure thermal expansions or sintering kinetics of any kind of materials, unlike traditional push rod dilatometer, it can push up to the dilatometric softening of the specimen. It is a device for measuring changes in the dimensions of a specimen, optically, the achieved resolution can results in greater values than those of a conventional pushrod dilatometer. A monochromatic light source, such as a laser , illuminates the specimen. Some of the light is reflected by the specimen and interferes with the incoming light, creating optical interference fringe s. As the specimen contracts or expands, there is a proportional movement of the interference fringes, which can be measured using a camera system. The measurement resolution is determined by the wavelength of the light, and is typically 0.5 micrometer m for blue light. Optical dilatometers are used to measure thermal expansion .

A cable of optical fiber , possibly concatenated into a dark fiber link, is the simplest form of an optical link. Other forms of optical link can include single colour links over a wavelength division multiplex infrastructure, and or links that use optical amplifier s to compensate for attenuation over long distances. Other forms of optical links include free space optical communication links. Also in the railways optical is used in two forms depending upon the whether the feeding station is main or not.
