Photonics Dictionary

multimode laser

A laser that produces emission in two or more transverse or longitudinal modes.

multimode optical waveguide

An optical waveguide that will allow more than one bound mode to propagate.

multiphase pinned operation

A method of reducing dark current in charge-coupled devices by holding all the clocks at negative voltage during the integration period.

multiphoton process

A process involving the interaction (absorption, emission or both) of two or more photons with a molecular entity.

multiple instruction/multiple data

A computer architecture used in parallel processing whereby all the processing elements are operating under their own local control rather than under the direction of a central control unit.

multiple invariance

Characteristic of optical correlators in which invariance to more than one distortion parameter per axis of the processor is obtainable.

multiple laser sequence

Also known as gatling gun laser. A system that has an array of lasers sharing a common central axis on a rotating Fabry plate to achieve increased laser firing rates by sequential Q-switching.

multiple lens block

A block that can hold more than one lens or blank.

multiple lens camera

A camera that uses a rotating mirror to project sequential images onto lenses that are arranged in an arc. The reflected images can then be recorded on stationary film. By using an 8-mm frame format,...

multiple slits

The series of equally spaced parallel slits that make up a scanning aperture in place of a single slit, in the scanning of a repetitive pattern.

multiple wavelength interferometry

A specific form of phase shifting interferometry - commonly referred to as multiple wavelength phase shifting interferometry - this form of interferometry utilizes two short wavelengths to synthesize...

multiple-beam laser

A laser having a Q-switching method that allows separate parallel volumes of the lasing material to act independently of each other and produce several separate beams. It is useful in high-speed...

multiplet

multiplex advantage -> Felgett advantage

The signal-to-noise ratio (SNR) obtained with a Fourier transform spectrometer when detector noise prevails, which exceeds the SNR of a scanning spectrometer in the same time by a factor proportional...

multiplex spectrometry

The recording and mathematical analysis of all spectral intervals of the spectrometer simultaneously.

multiplexing

The combination of two or more signals for transmission along a single wire, path or carrier. In most optical communication systems this is referred to as wavelength division multiplexing, in which...

multispectral imaging

Multispectral imaging is a technique that involves capturing and analyzing images at multiple discrete spectral bands within the electromagnetic spectrum. Unlike hyperspectral imaging, which acquires...

multispectral photography

The use of narrow bandpass filters and special photographic emulsions to discern features of a surface that would not be easily recognizable with regular black-and-white or color photographic methods.

multispectral scanner

An instrument used to record the emittance or reflectance of an object by scanning with discrete spectral resolution over a wide spectral band, or recording many discrete spectral bands...

multistripe array

A monolithic laser diode incorporating multiple coupled emitters.

MUM

maximum useful magnification

Munsell Book Of Color

A collection of color samples arranged in charts according to equal visually spaced steps in Munsell hue, value and chroma.

Munsell chroma

Numerical scale of chroma devised by A.H. Munsell and exhibited in the Munsell Book of Color.

Munsell color system

Founded by professor Albert Munsell. In the field of colorimetry, the Munsell color system is a color space that identifies a given color based on three different color measurements. These...

Munsell hue

Numerical scale of hue devised by A.H. Munsell and exhibited in the Munsell Book of Color.

Munsell notation

Alphanumerical description of color according to Munsell hue, value and chroma.

Munsell value

Numerical scale of lightness devised by A.H. Munsell and exhibited in the Munsell Book of Color.

Murty interferometer

A form of shearing interferometer that contains a simple wedged (plane-parallel) glass plate with a nonzero optical path difference to create interference between split optical wavefronts. The...

MUSE

multiple sub-Nyquist sampling encoding

mutual coherent function

A function that quantifies the performance degradation of coherent communications systems, imaging systems and all systems that rely on the spot size of a laser beam that has propagated along an...

MUX

MWIR

medium-wavelength infrared; mid-wave infrared

maxwell

Mylar

E.I. duPont's trade name for a polyester film. The most practical beamsplitter for use beyond the 15-µm wavelength because of its high efficiency. It exhibits high visible transmission, allowing...

myopia

A vision defect commonly referred to as nearsightedness. The defective condition results when the image of a distant object is focused in front of the retina by the relaxed eye. It can be corrected...

Mach-Zehnder

refractive index

Newton

nano-

N, n

A symbol used to represent the refractive index. It is commonly used with a subscript to represent the wavelength of light.

N-MCVD

nonsymmetrical modified chemical vapor deposition

N-type conductivity

In a semiconductor, the state created by the addition of a dopant that provides excess electrons.

N-type material

A quadrivalent semiconductor material, with electrons as the majority charge carriers, that is formed by doping with donor atoms.
