The optically induced leakage current is current which can be measured at transistor if LED = ”O(jiān)N” and LED =
”O(jiān)FF”.
LED of channel 1 is switched to ”O(jiān)N”.
At Tr-output of channel 2 a voltage is applied and one can measure a current between emitter and collector.
This is leakage current (at I

= 5 mA, V
