Pockels effect: transmitting information using modulated light
$1.00
This experiment shows how the Pockels cell can be used to transmit audio-frequency signals. The output signal of a function generator with an amplitude of several volts is superposed on a DC voltage which is applied to the crystal of the Pockels cell. The intensity of the light transmitted by the Pockels cell is modulated by the superposed frequency. The received signal is output to a speaker via an amplifier and thus made audible.
