CONTROLLING THE EFFICIENCY OF AN ELECTRONIC DEVICE |
摘要 |
An emitter of unbalanced pulse-modulated energy, specifically a laser, has a feedback circuit including a first branch detecting the mean amplitude of the emitted energy and a second branch detecting the peak amplitude of its pulses. The second branch includes a band-pass filter, centered on the pulse cadence, followed by a peak detector which may comprise a coherent demodulator driven by a square wave whose frequency corresponds to that cadence. The peak detector generates a control signal for a pulse former whose output signals are superimposed upon a biasing signal from the first branch before being fed to the modulating input of the energy emitter. |
