Photonics Dictionary

HTS

high-throughput screening

hub

The center of a local area network in the star topology.

Hubble effect -> redshift

The displacement of spectrum lines, as determined by the increasing distance between, and the relative velocity of, the observer and a light source, causing the lines to move toward the red portion...

Hubner rhomb

A glass rhomb that is used in photometry to compare two illuminated surfaces. This is accomplished by the rhomb's angles, which transmit two light beams, one from each of the two surfaces, so that...

HUD

head-up display

hue

The perceptual term for that aspect of color described by words such as red, yellow or blue. Achromatic colors, such as white, gray and black, do not exhibit hue.

Huefner spectrophotometer

A visual spectrophotometer with a rhomb located directly before the entrance aperture of a constant-deviation spectrophotometer.

Hurter-Driffield curve

A plotted relation between Log E (logarithm to base 10 of exposure in metercandle seconds) and density (logarithm to base 10 of opacity).

Huygenian eyepiece

An ocular having two planoconvex lenses that are formed from similar glass and that are separated by a space equal to half the sum of their focal lengths. This eyepiece is free of lateral chromatic...

Huygens principle

An analysis used for problems of wave propagation. The principle notes that each point of an advancing wavefront is the center of a new disturbance, the source of a new series of waves. It also notes...

HVEM

high-voltage electron microscope

HVL

half-value layer

HWFM

half wave full maximum

hybrid cable

A cable assembly containing both optical fibers and copper electrical conductors in the same jacket.

hybrid circuit

Any integrated circuit that also makes use of one or more discrete components; frequently used to describe circuits that combine both photonic and electronic components.

hybrid cooler

A cryogenic cooler device that is an intermittent Joule-Thomson refrigerator with a passive radiator serving as the precooler. Used for satellite applications, the device has Joule-Thomson and gas...

hybrid electromagnetic wave

A wave in the electromagnetic spectrum that has both electrical and magnetic field vectors in the direction of propagation.

hybrid focal plane array

A device where each pixel in the detector array is mated with a preamplifier on a single silicon chip, providing sensing and signal processing capabilities.

hybrid image recording device

A single housing that includes means of recording an image photographically and electronically.

hybrid mode

A mode possessing components of both electrical and magnetic field vectors in the direction of propagation.

hybrid mosaic on stacked silicon

A sensor module used in advanced pattern recognition systems, containing signal-processing integrated circuits stacked and connected by a busing circuit.

hybrid optical integrated circuit

Device in which the various circuit elements are fabricated in different substrate materials and then appropriately joined together so that the various substrate materials can be chosen to optimize...

hydrogel

A hydrogel is a three-dimensional network of polymer chains that are hydrophilic, meaning they have a strong affinity for water. This network structure allows hydrogels to absorb and retain large...

hydrogen cyanide laser

A gas laser having a mixture of gases that makes it useful in the lab. The mixture of gases flows through a pressure and gas-flow-rate-regulated, sealed vessel with such a gain that only the...

hydrogenated amorphous silicon

A photoreceptor material used in solar cells and in drums for laser printers and high-speed copiers because of its high quantum efficiency over a wide spectral band, high data-rate capability and...

hydrophilic

Hydrophilic is a term used to describe substances or materials that have an affinity for water. The word hydrophilic comes from the Greek words "hydro," meaning water, and "philos," meaning loving or...

hydrophobic

Hydrophobic is a term used to describe substances or materials that repel or do not readily interact with water. The word hydrophobic comes from the Greek words "hydro," meaning water, and "phobos,"...

hydroscopic

Designed to observe objects below the surface of water. Not to be confused with hygroscopic.

hydroxyl ion absorption

An optical fiber's absorption of electromagnetic waves due to hydroxyl ions remaining after contact with water.

hygroscopic

In fiber optics, a material whose properties, usually of transmission, are distinctly affected by the absorption of water vapor.

HYMOSS

hybrid mosaic on stacked silicon

Hypalon

E.I. duPont's trade name for a material used in the jacket of fiber optic cables. It is flame-retardant, thermally stable and resistant to oxidation, ozone and radiation.

hypercentric lens

A hypercentric lens refers to a lens system where the chief rays of light from an object are directed through the center of the lens aperture, ensuring that the entrance pupil is situated at...

hyperchromic shift

Hyperchromic shift refers to an increase in the absorption of light, leading to a higher absorbance, often observed in certain chemical or biological substances upon undergoing a structural change....

hyperfine splitting

The splitting of an element's spectral line as the result of the interactions between the electron spin and the spins of adjacent magnetic nuclei, or the presence of several isotopes in the sample...

hyperfocal distance

That object distance at which a camera must be focused so that the far depth of field just extends to infinity. The near limit of the depth of field is then half the hyperfocal distance. For normal...

hyperopia

A vision defect commonly referred to as farsightedness. Results when the image of a distant object is focused beyond the retina by the relaxed eye. The condition can be corrected by introducing a...

hyperplane eyepiece

hypersensitizing

With respect to photography, the process used to increase the effective speed of an emulsion between manufacture and exposure.

hyperspectral imaging

Hyperspectral imaging is an advanced imaging technique that captures and processes information from across the electromagnetic spectrum. Unlike traditional imaging systems that record only a few...

hyperspectral imaging camera

A hyperspectral imaging camera is a sophisticated imaging device capable of capturing and processing data across a wide range of wavelengths within the electromagnetic spectrum, typically from...

hyperspectral resolution

Hyperspectral resolution refers to the level of detail or granularity in the spectral information captured by a hyperspectral imaging system. In hyperspectral imaging, the electromagnetic spectrum is...

hyperstereoscopy

A type of stereoscopic photography in which the distance between the two view points is greater than the average interpupillary distance. Therefore, the viewed image will appear to be half its size...

hysteresis

This term literally means "to lag behind.'' It is quite often used to describe the residual effect that remains after the primary effect has been removed, or the lag that exists between the...

hertz

I/O

input/output

IAD

ion-assisted deposition

IBA

inhomogeneously broadened absorber
