Abstract
An optoelectronic device for use in an optical detector module of a meter comprising a rotary member having a reflective sector comprises a voltage edge source, a sender comprising a light-emitting diode emitting a light pulse in response to a current pulse, a receiver, and a voltage source. The sender comprises a capacitor and a resistor connected on one side to the voltage source and the capacitor is connected on one side to the voltage edge source and on the other side to the other side of the resistor and to the anode of the light-emitting diode.
Claims8
An optoelectronic device comprising:
- a voltage edge source:
- a sender having a light-emitting diode emitting a light pulse in response to a current pulse;
- a receiver;
- and
- a voltage source, in which device said sender has a capacitor and a resistor connected on one side to said voltage source and said capacitor is connected on one side to said voltage edge source and on the other side to the other side of the resistor and to the anode of said light-emitting diode, the resistance of said resistor being selected to bias said diode whilst maintaining a low forward current in said diode and the light pulse emitted from the light-emitting diode being proportional to the voltage supplied by said voltage source.
