Abstract:
A device such as a laser diode is provided with a monitoring arrangement. The monitoring arrangement has voltage to current convertors arranged to provide respectively currents which are proportional to the respective voltages on an anode and on a cathode of the laser diode. The monitoring arrangement provides a first output signal when the laser diode is on too long. That output signal is used to cause the laser diode to be switched off.
