LED illumination device for a scannerless range imaging system |
摘要 |
A light emitting diode (LED) illumination device for generating modulated light for a scannerless range imaging system includes circuitry for generating a drive signal having a given phase and frequency characteristic; a plurality of light emitting diodes arranged in a plurality of LED banks, wherein each LED bank comprises a plurality of light emitting diodes connected in series to the circuitry to receive the drive signal; and a switching stage for simultaneously activating the plurality of LED banks such that the LED banks generate the modulated light according to the phase and frequency characteristics of the drive signal.
