Coherence length
| Glossary Of Laser Terminology |
- A measure of temporal coherence, expressed as the propagation distance over which the coherence significantly decays
- That length over which energy in two separate waves remains constant. with respect to a laser, the greatest distance between two arms of an interferometric system for which suficient interferometric effects can be obtained.

Coherence, английский
- Соответствие; согласованность
- Lasers and leds emit coherent light waves that are in phase with one another. describes properties of the correlation between a single wave, or between several waves or wave packets. when interfering, two waves can add together to create a wave of greater amplitude than either one (constructive interference) or subtract from one another to create a wave of lesser amplitude than either one (destructive interference)
- A property of electromagnetic waves which are in phase in both time and space. coherent light has monochromaticity and low beam divergence, and can be concentrated to high power densities. coherence is needed for interference processes like holography.
- The alignment between light wave wavelength and the position of that wave in its oscillation cycle. when the crests and troughs of several light waves are in alignment, they are coherent. collimated light
- A fixed phase relationship between the electric field values at different locations or at different times
- И coherency

Length, английский
- Длина
- Dimension of label along the web direction
- The distance between the lens of the eye and the point behind the lens where light is focused
- The distance or period of time between a specified start point and a specified end point. for example, the length of an audio or video clip is usually measured in minutes and seconds. lens (n)

Length - to - width ratio, английский
A comparison of the length and width of the girdle outline on fancy shaped diamonds. the ratio is found by dividing the length of the diamond by the width. the width is always stated as 1.
