PHOTOELECTRONIC MIXING DEVICE (PMD) SYSTEM

摘要

The PMD system comprises at least one PMD element (PMD), at least one transmitter (E), whose intensity can be modulated, and at least one controlling electronic device (FG) by means of which the PMD element (PMD) and the transmitter (E) can be controlled with at least one respective modulation voltage (Umod, Umod, UTxmod), and by means of which a phase shift ( DELTA f) can be altered by an actuating signal. The PMD system is characterized in that a controlled system (CTR) is provided into which at least one output signal (Ua, Ub, Ud) of the PMD element (PMD) can be fed as a controlled variable (U'd) and whose output signal (U1phs, U1fc) can be fed into the controlling electronic device (FG) as an actuating signal, whereby the controlled variable (U'd) can be set to the value of a predetermined target variable by the controlled system (CTR).
