Meaning of dark current in English:

dark current

noun

  • The residual electric current flowing in a photoelectric device when there is no incident illumination.

    ‘When an ignition switch is OFF, only the sub converter supplies the dark current to the low voltage load and the main DC-DC converter is turned OFF.’
    • ‘No photoinduced electric signal was observed except the light independent current, the so-called dark current, which was from potential differences between electrodes.’
    • ‘We define the dark current noise, or dark-current shot noise (i sd), as where q is the electron charge and I d is the dark current.’
    • ‘The use of 3 - D DROCs results in improved QEs and narrow spectral responses, while the reduction in MQW area and in number of wells promotes lower dark current and higher photoconductive gain, respectively.’
    • ‘Background noise in the camera is limited by readout noise: 0.5 counts/pixel/s comes from dark current and 5.9 counts/pixel/s from readout noise.’
    • ‘First the pointwise current is integrated over the lateral boundary of the rod outer segment and suppression of dark current is computed.’
