Photon, английский
- The photon is the elementary particle of electromagnetic energy and represents quanta of energy. for radiation protection purposes they are represented by gamma rays and x-rays photons (non-ionising radiation would of course include light photons). they a
- In quantum theory, the elemental unit of light, having both wave and particle behavior. it has motion, but no mass or charge. the photon energy (e) is proportional to the em wave frequency (v) by the relationship e=hv, where “h” is planck`s constant (6.63 x10-34 joule-sec). also, particle with energy equal to a single quanta. the energy of the particle is proportional to frequency. electromagnetic energy may sometimes be considered to be wave-like, and at other
- A particle of light that acts as an individual unit of energy.
- Particle of electromagnetic radiation.
- Particle of light, hypothesized to explain those behaviors of light in which its behavior is corpuscular rather than wavelike.
- Particle of light, hypothesized to explain those behaviors of light in which its behavior is corpuscular (in other words, like small particles) rather than wavelike.
Photon (rt), английский
An electromagnetic packet of radiation. it has a dual character, acting sometimes like a particle and at other times like a wave. photons all have equal velocity (the speed of light), have no electric charge, and have no mass.
Photon welding, английский
Photonega, английский
Photonic, английский
A term coined for devices that work using photons or light, analogous to "electronic" for devices working with electrons.
Photonic band-gap structure, английский
Variable compositions
Photonic bandgap fibers, английский
Optical fibers where light is guided based on a photonic bandgap effect
Photonic crossconnect, английский
Оптический кросс-соединитель
Photonic crystal, английский
Photonic crystal fibers, английский
Specialty optical fibers with a built-in microstructure, in most cases consisting of small air holes in glass
Photonic crystal fibre, английский
Photonic crystal heterostructure, английский
Photonic integrated circuit, английский
Photonic integrated circuits, английский
Integrated circuits with optical functions
Photonic metamaterials, английский
Nanostructured materials with special optical properties
Photonics, английский
- Gallium arsenide integrated circuits for optical interconnections within and between computer and communication equipment called gaa. present fiber optic computer and communication links are limited by discrete component electronics. in development is a projected 32-channel parallel monolithic ic connector which could vastly increase performance and drive down costs to open up long- sought new fiber optic markets which can replace current copper-wired connections.
- The electronic technology involving light and photons at all wavelengths between the far-infrared and the ultra-violet. also called "optoelectronics".
- The science and technology of light
Photonics mast, английский
A device similar in concept to a submarine periscope, that provides many benefits a periscope is unable to offer. it replaces line-of-sight viewing with equipment, similar to a digital camera, mounted on telescoping arms that are contained entirely within the sail without penetrating the pressure hull. the hull opening for cables is much smaller and more easily sealed, minimizing the risk of water leakage. moreover, being connected by flexible cables instead of rigid tubes, the control room need not be placed directly below the sail, but can be moved to a lower deck away from the hull’s curvature where there is more space. sailors throughout the boat can view color, highresolution black and white, or infrared images, on flatpanel displays; and these images can be shared with other ships in the theater, or with command centers ashore. however, photonic masts can not operate at the depths possible for floating fiber optic scanners.
Photons, английский
- Quanta of light energy
- Quanta of electromagnetic radiation. light can be viewed as either a wave or a series of photons.
Photonuclear, английский
Pulse, английский
- A discontinuous burst of laser, light or energy, as opposed to a continuous beam. a true pulse achieves higher peak powers than that attainable in a cw output.
- A current or voltage which changes abruptly from one value to another and back to the original value in a finite length of time. used to describe one particular variation in a series of wave motions. the parts of the pulse include the rise time, fall time, and pulse width, pulse amplitude. the period of a pulse refers to the amount of time between pulses.
- Pulso
- The regular expansion and contraction of an artery caused by the heart pumping blood through the body, which can be felt with the fingers especially where an artery is near the surface of the body, as in the wrist or neck her pulse is very irregular. to take or feel a person’s pulse to measure a person’s pulse rate by pressing on the skin above an artery with the fingers has the patient’s pulse been taken? comment: the standard adult pulse is about 72 beats per minute, but it is higher in children. the pulse is usually taken by placing the fingers on the patient’s wrist, at the point where the radial artery passes through the depression just below the thumb.
- A brief emission of radio energy by a radar system. the detection and ranging part of the acronym is accomplished by timing the delay between transmission of radio energy and its subsequent return.
- Импульс
- Heart rate. normal adult resting heart rate varies among horses but is usually 40 beats per minute.
- Transient electrical or ultrasonic signal that has a rapid increase in amplitude to its maximum value, followed by an immediate return.
- Transient electrical or ultrasonic signal that has a rapid increase in amplitude to its maximum value, followed by an immediate return.16
