photoconductive cell
  • pooljuhtelement, mille takistus väheneb valguse, infrapuna- või ultraviolettkiirguse toimel
  • type of resistor whose resistance decreases when the intensity of light increases
  • passive component that decreases resistance with respect to receiving luminosity (light) on the component's sensitive surface
fototakisti preferred
Usage examples
  • Fototakisti takistus väheneb juhusliku valguse intensiivsuse suurenemisega, ehk teisisõnu, sellel on fotojuhtivus, mille tõttu saab fototakistit rakendada valgustundlikes detektorahelates ning valgusaktiveeritud ja tumedalt aktiveeritud lülitusahelates, mis toimivad takistuspooljuhina.
fotoresistor
photoresistor preferred
Usage examples
  • The resistance of a photoresistor decreases with increase in incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive detector circuits and light-activated and dark-activated switching circuits acting as a resistance semiconductor.

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.
