  • elektrooptilise kaugusmõõturi oluline element, mis toodab ja kiirgab mõõtesignaali jaoks vajalikku energiat
  • essential element of the electro-optical distance meter, which produces and emits the energy for the measuring signal
valgusallikas preferred
Usage examples
  • Valgusallikas, milleks peamiselt kasutatakse tahket laserit või kollimeeritud LED-i, kiirgab energiat elektromagnetlainena kandes mõõtesignaali, mis tavaliselt saadakse kiirguslaine moduleerimise teel.
allikas
light source preferred
Usage examples
  • The light source emits the energy as an electromagnetic wave. It carries the measuring signal which is normally obtained by modulation of the emitted wave. The light sources mainly used are the solid laser or collimated LED.

Domain metrologymeasuring instruments
  • ühisfookuselise värvsussondi valgusallikas, mis sisaldab lainepikkuste pidevust eelnevalt määratletud spektripiirkonnas
  • optiline seade, mis kiirgab valgust sobiva lainepikkuste vahemikuga kindlaksmääratud spektripiirkonnas
  • confocal chromatic probe source of light containing a continuum of wavelengths in a predefined spectral region
  • optical device emitting light with an appropriate range of wavelengths in a specified spectral region
  • source of light containing a continuum of wavelengths in a predefined spectral and spatial range
valgusallikas
Usage examples
  • Värvsussondi valgusallika kiiratav spektripiirkond peab ühilduma optikasüsteemi ja detektori spektriribaga.
  • Igat valgust kiirgavat allikat nimetatakse tavaliselt valgusallikaks, st et päike, tähed, tuli, küünlad ja elektripirnid on kõik valgusallikate näited, kuna nad kiirgavad valgust, öeldakse, et nad on helendavad.
light source
Usage examples
  • The spectral region of the light source of the chromatic probe emitted with the spectral bandwidth of the optical system and the detector.
  • A source that gives out light is called a light source. The sun, stars, fire, candles, electric bulbs are all the examples of light sources. As they radiate light, they are said to be luminous.
