Photonics Dictionary

optogenetic defibrillation

An optogenetic technique that embeds genetically-engineered proteins to the heart to aid in terminating arrhythmias. After the proteins are embedded in the heart, it can be defibrillated by pulses of...

optogenetics

A discipline that combines optics and genetics to enable the use of light to stimulate and control cells in living tissue, typically neurons, which have been genetically modified to respond to light....

optoisolator

An optical coupling device that uses light to bridge the gap between incompatible wire communications systems. It contains an input amplifier, a light-emitting diode, a photodiode and an output...

optomechanical

Optomechanical refers to the integration of optical and mechanical systems or components. In optomechanical systems, optics (related to the manipulation of light) and mechanics (related to the...

optometer

An instrument designed to measure the refractive power and range of accommodation of the eye. See ophthalmic instruments.

outside radius

orange peel

In the context of imaging, particularly digital imaging and printing, "orange peel" refers to a texture or visual distortion that resembles the surface of an orange peel. This texture can result from...

ORD

optical rotary dispersion

ordinary ray

The ray that has an isotropic speed and maintains a uniform polarization in all propagation directions when traveling in a doubly refracting (birefringent) crystal. It obeys Snell's law upon...

ORFE

optical receiver front end

organic dye

Any organic substance, that when dissolved in appropriate liquid based solvents will absorb and emit electromagnetic radiation in the near ultraviolet, visible and near infrared spectral regions....

organic dye laser

A laser having a lasing material that is a fluorescing organic dye. Depending on the dye used, it can produce emission in any part of the visible spectrum into the near-infrared and ultraviolet, and...

organic light-emitting diode

An organic light-emitting diode (OLED) is a type of light-emitting diode (LED) technology that utilizes organic compounds to produce light. OLEDs are commonly used in display technologies, such as...

organometallic chemical vapor deposition -> metallorganic chemical vapor deposition

A method of growing single crystals in which atoms and molecules from gaseous organic compounds interact and form a layer on a single-crystal substrate.

oriented crystal

A crystal having the axes of its grains aligned so that they have directional magnetic characteristics.

oriented lenticular screen

A lenticular screen having the lenticules tipped about 20° to compensate for off-normal projection.

ORMOSILS

organically modified silicates

ORP

oxidation-reduction potential

ORRAS

optical research radiometrical analysis system

orthicon

A television camera tube in which a low-velocity electron beam scans a photoactive mosaic that has been created by an optical image. Once scanned by the electron beam, the electrical storage capacity...

orthochromatic film

Black and white film that is sensitive to green, blue and violet light but not to red light.

orthographic camera

A camera designed with a telecentric optical system and a narrow field of view; the telecentric optical system (placement of the system's stop at its focal point) ensures that the principal image...

orthonormalization

Optimization method used in optical design computer programs that employs a variable-by-variable approach to construct new variables that are orthogonal. This technique can uncover solutions that...

orthorhombic

Having three unequal angles perpendicular to each other.

orthoscopic

Corrected for distortion.

orthoscopic eyepiece

A telescopic eyepiece that produces a field of view between 40° and 50°. The eyepiece consists of a single element eyelens that is normally plano convex, and a cemented triplet that is...

orthotropic

Having a longer axis that is relatively vertical.

OSA

The Optical Society, formerly called Optical Society of America; optical spectrum analyzer

OSCI

Office of Standards Code and Information

oscillation threshold

Point at which a laser's material gain is equal to, or greater than, the circuit losses.

oscillator -> laser cavity

A laser cavity, also known as an optical cavity or resonator, is a fundamental component of a laser system. It is a confined region or space where light undergoes multiple reflections, leading to the...

oscillogram

A record formed when the luminous trace or image produced by an oscilloscope is photographed.

oscillograph

An instrument used to record rapidly varying currents or voltages. An oscillograph may consist of a cathode-ray tube oscilloscope with a camera attachment, or a mirror galvanometer with a lamp and...

oscillography

The graphic recording of physical changes vs. time, in electrical quantities, using an oscilloscope.

oscilloscope

A system in which a supplied signal causes the deflection of the electron beam in a cathode-ray tube, thus forming a visible trace on the phosphor screen of the tube and providing for examination of...

OSF

optically shaped film

OSHA

Occupational Safety and Health Administration

OSMA

optical spectrometric multichannel analyzer

ospin

Opsins are a group of light-sensitive proteins found primarily in the retinas of vertebrate and invertebrate eyes, as well as in other light-sensitive tissues. These proteins play a crucial role in...

OSR

optical solar reflector

OSS

optical sensor system

Ostwald system

The system of color classification and description produced by Wilhelm Ostwald.

optical thickness

OTA

Office of Technology Assessment

OTDR

optical time-domain reflectometer

OTF

optical transfer function

OTIM

optical transform image modulation

otoscope

An otoscope is a medical device used by healthcare professionals, particularly ear, nose, and throat (ENT) specialists, primary care physicians, and pediatricians, to examine the ear canal and...
