Photonics Dictionary

The photographic recording of an action by taking a series of still pictures at regular intervals throughout the action.

chuck

In the optical field, a tube to which a lens is fastened for centering.

chuck mark

The mark formed when the movement of the lens over the face of the centering chuck abrades the surface.

curie

CID

charge-injection device

CID -> charge-injection device

A charge-injection device (CID) refers to a class of devices that manipulate and detect electrical charge within a semiconductor material. Charge-coupled devices are a specific implementation of this...

CID camera

CID, or charge injection device, camera refers to a type of imaging device that utilizes a specific kind of solid-state image sensor technology. CID cameras are capable of capturing images in a...

CIE

Commission Internationale de l'Eclairage, the international commission on illumination.

CIE

Commission Internationale de l' Eclairage (International Commission on Illumination)

CIE coordinates -> chromaticity coordinates

Proportions of standard primaries (tristimulus values) required for a color match; ratios of each tristimulus value of a color to their sum. In the CIE colorimetric system, designated X, Y and Z.

CIE illuminant

Spectral power distribution representing a standard source of illumination, which may be real or hypothetical.

CIE observer

Hypothetical observer having standard color vision as described by standard color-matching properties.

CIE source

Standard light source representative of the quality of specified natural or artificial illumination.

CIE system

Methodology for specifying color based on the CIE sources, observers, and coordinate system.

CIG

computer image generation

CIM

computer input from microfilm; computer-integrated manufacturing

cine camera

A camera capable of making successive exposures on a continuous film driven by accurately spaced sprocket holes (a motion picture camera).

cine fluorography

The application of a cine camera in recording the images on a fluorescent screen. When x-rays are used to produce the screen images, this process is referred to as cine-radiography.

cinematography

The technique of making motion pictures.

cinemicrography

Cinematography performed with the use of a microscope to film the actions of microscopic specimens.

cineradiography

The photographic filming of the action of x-ray images recorded on a fluorescent screen by means of large lens apertures and highly sensitive filters.

cinesextant

An optical instrument used to track and image a test vehicle (target) throughout its flight. The cinesextant frequently includes multiple devices such as high-speed video and film cameras as well as...

cinetheodolite -> phototheodolite

A camera equipped with angular scales in altitude and azimuth. The scale readings are imprinted on the film when an exposure is made. The exact point indicated by the scale readings is shown by...

CIP

cold isostatic pressing

CIPS

communications, information and processing services

CIRC

cross-interleaved Reed-Solomon code

circle of confusion

The image of a point source that appears as a circle of finite diameter because of defocusing or the aberrations inherent in an optical system.

circle of least confusion

Best point of focus for an image in a beam of light at the smallest cross section of the beam.

circle, aiming -> aiming circle

An instrument designed to measure angles in azimuth; used in general topographic work and military gunnery.

circular birefringence

The optical phenomenon in which right circularly polarized light transmitted by an active medium travels at a different velocity than that of left circularly polarized light.

circular dichroism spectroscopy

A type of spectroscopy used extensively in the analysis of biological samples. Because most biologically synthesized molecules, such as proteins, are optically active, circular dichroism spectroscopy...

circular dichroism

Circular dichroism (CD) is a spectroscopic technique used to study the structural characteristics of chiral (asymmetric) molecules, particularly biomolecules like proteins, nucleic acids, and certain...

circular scanning

Scanning characterized by the generation of a plane or right circular cone with a vertex angle of about 180° by the direction of maximum radiation.

circular variable filter

An optical interference coating, vacuum-deposited on a circular substrate, whose transmission characteristics may be varied by physical rotation.

circularly polarized light

A light beam whose electric vectors can be broken into two perpendicular elements that have equal amplitudes and that differ in phase by l/4 wavelength.

circulator

A passive device, having three or more ports, in which input light from one port is coupled only to the next sequential port in a given direction and is prevented from traveling in any other...

circum

circumference

circumzenithal arc

The halo phenomenon of a brightly colored arc having the colors of the rainbow and lying parallel to the horizon.

CIS

compensated imaging system

cathodoluminescence

CLA

center line averaged

cladding

The low-refractive-index material that surrounds the core of an optical fiber to contain core light while protecting against surface contaminant scattering. In all-glass fibers, the cladding is...

cladding glass

In fiber optics, the glass that is found around the glass core of the fiber, and that has a lower refractive index than the fiber.

cladding mode

A mode that is confined by virtue of a lower-index medium surrounding the cladding. Cladding modes, in the terminology of mode descriptors, are equivalent to cladding rays in the terminology of...

cladding mode stripper

A mechanism or device, especially a coating with a refractive index equal to or slightly greater than that of an optical fiber's cladding, that removes modes propagating through the cladding by...

cladding ray

A ray that is reflected into the core of an optical fiber from the outer surface of the cladding.

CLASP

closed-loop adaptive single parameter

classification duration

For a laser, the maximum exposure time that the laser design allows; 0.25 seconds for a Class 2 laser.

Clayden effect

The desensitization of the first photographic exposure after it has been subjected to high-intensity radiation.

cleaning equipment

In optics, degreasers or ultrasonic arrangements used for removing pitch, cement or polishing material from lenses during manufacture. It also may refer to manual cleaning devices used immediately...
