electro-optic Fabry-Perot spectroscopy
The spectroscopic analysis of interference patterns using an electronic imaging tube with a Fabry-Perot interferometer to record the fringes.
electro-optic modulator
An electro-optic modulator (EOM) is a device used to modulate the amplitude, phase, or polarization of light waves using an external electrical signal. Electro-optic modulation is a fundamental...
electro-optics
1. The branch of physics that deals with the use of electrical energy to create or manipulate light waves, generally by changing the refractive index of a light-propagating material; 2....
electromagnon
An electromagnon is a quasiparticle excitation that combines aspects of both magnetism and electric polarization in a crystal lattice. Specifically, it refers to a collective excitation of spins and...
electron multiplication charge-coupled device camera
An EMCCD (electron-multiplying charge-coupled device) camera is a type of scientific camera specifically designed for low-light imaging applications that require high sensitivity and fast readout...
electron optics
The control of free electron movement through the use of electrical or magnetic fields, and use of this electron movement in research investigation of electronic diffraction phenomena, directly...
electron-beam lithography system
An electron-beam lithography (EBL) system is a sophisticated nanofabrication tool used in the semiconductor industry and research laboratories to pattern extremely fine features with sub-micrometer...
electronic band edge
The point at which short-wavelength transmission is cut off.
electronic band spectrum
The bands of spectral lines representing the electronic transition in a molecule.
electronic flash unit
A small xenon-filled tube with metal electrodes fused into the ends. The gas flashes brilliantly when a condenser is discharged through the tube. The duration of the flash is primarily dependent upon...
electronic line scanning
A method that uses electronic means to move the scanning spot along the scanning line.
electronic photometer
->
photoelectric photometer
Also known as electronic photometer. A photometer with a photocell, phototransistor or phototube for measuring the intensity of light.
electronic shutter
A mechanical shutter that has had its timing escapement replaced with an electronic timing circuit. This circuit allows a wider range of exposure times, can be more accurate, and, placed in a circuit...
electronic video recording
A term applied to the recording of video images by means of magnetic tape or disc, so that the image's record can be played back in a video format at a later time.
electronic viewfinder
A small television monitor that replaces the reflex viewfinder in a television camera.
electronic windowing
In target tracking, a technique for speeding up the image processing by removing bunches of pixels that are outside the area of interest.
electronically controlled coupling
The use of an electric field or signal to couple a lightwave from one dielectric waveguide into another dielectric waveguide.
electrophoretic display
An electrophoretic display, often referred to as an electronic paper display or e-paper display, is a type of electronic visual display technology used in electronic devices for the purpose of...
electrostatically focused image tube
An image intensifier that uses electrostatics to amplify and focus the electronic image.
electrowetting display
An electrowetting display (EWD) is a type of electronic display technology that utilizes the principles of electrowetting to control the behavior of colored oil droplets on a hydrophobic surface....

epitaxial
Epitaxial refers to the growth of a crystalline layer on a crystalline substrate in such a way that the orientation of the crystal lattice of the growing layer is related to that of the substrate. In...
epitaxial deposition
Epitaxial deposition is a process used in semiconductor manufacturing and materials science to grow a thin crystalline layer, known as an epitaxial layer, on a substrate. The term epitaxial refers to...
epitaxial equipment
Epitaxial equipment refers to a set of specialized tools and systems used in the process of epitaxy, which is the growth of crystalline layers on a substrate material. Epitaxial growth is a critical...
equidensitometry
1. The use of an electronic microdensitometer to measure points of equal density on a photographic deposit. 2. A technique that simplifies a picture's density pattern by making a single isodensity...
