Photonics Dictionary

chromatic resolving power

The ability of the instrument to separate wavelengths that are close together, numerically equal to the ratio of the shorter wavelength to the difference between two wavelengths that can just be...

chromatic vision -> color vision

Color vision refers to the ability of organisms to perceive and distinguish different wavelengths of light as different colors. It is a sensory ability that allows humans and many other animals to...

chromaticity

The qualities of color associated with hue and saturation, but not brightness or lightness.

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.

chromaticity diagram

The plane diagram produced by plotting one of the three chromaticity coordinates (X,Y,Z) against another. The most common diagram is the CIE (X,Y) diagram, which is plotted in rectangular coordinates.

chromaticness

The sensations of hue and saturation, taken together, but not brightness or lightness.

chromatography

The chemical method of separating compounds dissolved in one phase (usually mobile) through its equilibration with a second phase (usually stationary). The mechanism of separation may involve...

chrominance

The difference between any color and a reference color having equal luminance and a specified chromaticity.

chromoendoscopy

A technique of using dyes during endoscopy to improve tissue differentiation. Dyes such as methylene blue, Toluidine blue and Lugol's solution all have the ability to stain particular types of cells....

chromophore

A naturally occurring pigment in tissue that may selectively absorb certain wavelengths and can be used to aid in targeting the beam in laser surgery.

chromosphere

A layer between the corona and the photosphere of the sun; its emission is overwhelmed by light emitted by the underlying, denser photosphere.

chronophotograph

The continuous record containing the series of pictures formed by chronophotographic methods.

chronophotography

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.

circular-ranging optical coherence tomography

Circular-ranging optical coherence tomography (CR-OCT) is a specialized imaging technique used in medical diagnostics and research to obtain high-resolution cross-sectional images of biological...

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
