linar

Celestial point sources that emit specific wavelengths of radiation that appear on spectral charts as narrow lines. The term linar is a contraction of line and star.

line of sight

The line of vision; the optical axis of a telescope or other observation system. The straight line connecting the object and the objective lens of the viewing device.

line scan

Line scan refers to a method of capturing images or data by scanning a single line at a time, as opposed to capturing the entire image simultaneously. This technique is commonly used in various...

line source

In the spectral sense, an optical source that emits one or more spectrally narrow lines as opposed to a continuous spectrum. In the geometric sense, an optical source whose active (emitting) area...

line spectra

Spectra that originate from atoms; they are composed of lines having irregular spacing and intensity.

line spectrum

A spectrum formed by radiation whose energy values of the property being measured cluster about at least one discrete value, as opposed to a continuous spectrum. The actual width of the spectral line...

line spread function

The intensity distribution seen when scanning the image of a line, in the direction perpendicular to that line.

line-narrowed laser

A semiconductor laser in which the naturally occurring broad linewidth has been narrowed by incorporating the laser diode into a large resonant external cavity.

line-scan camera

A line-scan camera, also known as a line-scan image sensor or linear array camera, is a type of digital camera designed to capture images one line or row of pixels at a time, rather than a full...

line-scan recording

A type of recording in which the recording line remains fixed and the recording medium is fed past the recording device.

line-selectable laser -> tunable laser

Any form of laser; e.g., a dye laser, having an output that can be adjusted over a wide range of wavelengths. Normally the range is about 70 nm wide.

lineament

A mappable surface feature arranged in straight or curved lines that is distinguished from surrounding surfaces and is formed as a result of the landform's internal characteristics.

linear accelerator

linear actuator

High-precision motorized positioning device, often linked to computer control equipment.

linear amplifier

Amplifier in which the input and output pulse heights are directly proportional.

linear array

A solid-state video detector consisting of a single row of light-sensitive semiconductor devices, used in linear-array cameras.

linear element

A device for which the output electric field is linearly proportional to the input electric field, and no new wavelengths or modulation frequencies are generated.

linear encoder -> optical encoder

A device designed to measure linear or rotary motion by detection of the movement of markings on a transparent medium past a fixed point of light. The encoder has a moving code plate, a glass disc...

linear energy transfer

The transfer of energy lost by radiation to the body, relative to the loss of energy per unit of path traveled.

linear field

The measured width of the field of view at any distance.

linear image sensor

A linear image sensor is a type of solid-state electronic device used to capture and convert light into electrical signals. Unlike area image sensors (such as CCD or CMOS sensors), which capture an...

linear optics

Linear optics refers to the study and manipulation of light in a linear and deterministic manner, where the response of optical elements is proportional to the amplitude of the incident light wave....

linear plastic

A term for thermoplastic optical materials; that is, those in which the polymer chains remain linear after heating and molding and which thus can be remolded again and again, unlike thermoset...

linear polarization

See plane-polarized light; polarization.

linear positioning stage

A linear positioning stage, also known as a linear stage or translation stage, is a precision mechanical device used to accurately move and position objects along a linear axis. These stages are...

linear receive optics

Linear receive optics typically refers to the optical components and systems used in the reception (detection) of linearly polarized light signals in various applications, such as optical...

linearity

A relationship between two variables so that when plotted on a graph they yield a straight line.

lineation

Subsurface linear arrangement of elements of rock that is not mappable; lineation is a one-dimensional characteristic.

linewidth

1. The range of frequencies or wavelengths over which radiations are absorbed or emitted in a transition between a specific pair of atomic energy levels. The full width is determined between...

link

In data communications, the instrumentation connecting two stations: transmitters, receivers and the cable that runs between them.

Linnik interference microscope

A Michelson-type interference microscope used to produce interference patterns of reflective specimens through the interference between light reflected by the specimen and that reflected by a...

LINS

laser inertial navigation system

thermoplastic material -> linear plastic

A term for thermoplastic optical materials; that is, those in which the polymer chains remain linear after heating and molding and which thus can be remolded again and again, unlike thermoset...

3D laser line profile sensor

A 3D profile sensor, also known as a 3D profiling sensor or 3D depth sensor, is a technology that is used to capture and measure the three-dimensional shape or profile of an object or a scene. These...

absorption line

The wavelength or frequency corresponding to an absorption resonance with a given molecular or atomic species. The line spectrum will vary with the element as well as the molecular compound.
