light-dependent resistor variant
LDR variant
  • fotoelektriline tundlik element, mis kasutab mõõtmiseks optilise kiirguse põhjustatud elektronide emissiooni
  • photoelectric detector that utilizes for measurement the emission of electrons caused by optical radiation
  • gas-filled or vacuum tube that is sensitive to light
fotoemissioontajur preferred
Usage examples
  • Fotoemissioontajureid kasutati varem laialdasemalt, kuid nüüd on need paljudes rakendustes asendatud tahkis-fotodetektoritega.
fotoemissioonsensor
fotoemissioonandur former
phototube preferred
Usage examples
  • Phototubes were previously more widely used but are now replaced in many applications by solid state photodetectors.

photoemissive cell
  • gaasiga täidetud või vaakumtoru, mis on valguse suhtes tundlik
  • gaasiga täidetud element fotoelektrilise efekti demonstreerimiseks lihtsate mõõtevahenditega õpilastele kasutamiseks, mis näitab ka seda, kuidas elektronide emissioon suureneb valguse intensiivsuse suurenemisega
  • fototoru, kus teatud valgustuse saavutamisel voolab elektrivool
  • gas-filled or vacuum tube that is sensitive to light
  • gas-filled cell for demonstrating the photoelectric effect with simple measuring instruments for use by students that also shows how the emission of electrons increases with increasing light intensity
  • phototube in which an electric current flows when a certain illumination is reached
ioonfotoelement preferred
Usage examples
  • Ioonfotoelementi kasutatakse nt releena.
Good to know
  • Ioonfotoelementi ehk gaasi- või vaakumtoru nimetatakse õigemini „fotoemissioonrakuks“, et eristada seda fotogalvaanilistest või fotojuhtivatest rakkudest.

gas-filled photocell preferred
Usage examples
  • Gas-filled photocell used as a relay.
Good to know
  • Such a gas-filled photocell is more correctly called a "photoemissive cell" to distinguish it from photovoltaic or photoconductive cells.
