Joule (j)
| Glossary Of Laser Terminology |
A unit of energy (1 watt-second) used to describe the rate of energy delivery. it is equal to 1 watt-second or 0.239 calorie. a basic unit of energy. a 1 watt transmitter radiates 1 joule of energy every second. joule/cm2 is a unit of radiant exposure used in measuring the amount of energy incident upon a unit area.

Joule, английский
- The joule (j) is the si unit of energy. one joule is the energy expended when a force of one newton is applied over a displacement of one meter in the direction of the force. the use of the joule is probably limited in radiation protection but is used in
- A unit of work, energy, or heat. 1j (joule)=1 nm) (newton meter).
- Джоуль
- A unit of energy or work; equals the work done by a force of 1 newton which acts over a distance of 1 metre in the direction of the force.
- The si unit of measurement of work or energy. 4.184 joules equals one calorie. symbol j
- A metric unit of energy or work; 1 joule per second equals 1 watt or 0.737 foot-pounds; 1 btu equals 1,055 joules.
- A metric unit of energy or work; 1 joule per second equals 1 watt or 0.737
Joule (symbol j), английский
The joule is the derived unit of energy in the international system of units. it is the energy exerted by a force of one newton acting to move an object through a distance of one meter. in terms of dimensions- 1 j = n m = kg m/s^2* m=kg m^2/s^2
Joule`s law, английский
Transmitter, английский
- Передатчик; датчик
- Передатчик
- A device that includes a source and driving electronics. it functions as an electrical-to-optical converter.
- Измерительный преобразователь
- (1) transducer that emits ultrasonic energy. (2) electrical circuits that generate the signals emitted by the transducer. transverse vertical (polarized) wave: transverse wave in which the plane of vibration is normal to the incidence surface.
