    • The invention relates to an electronically commutated electric motor comprising a stator and an especially permanent-magnetic rotor. The electric motor also comprises a control unit which is effectively connected to the stator and is designed to generate control signals for commutating the stator in such a way that the stator can generate a rotating magnetic field in order to rotate the rotor. The electric motor further comprises at least one rotor position sensor which is designed to detect a position, especially an angular position, of the rotor and generate a rotor position signal representing the position of the rotor. The control unit is designed to generate the control signals in accordance with the rotor position signal. According to the invention, the control unit is designed to sample and quantize the rotor position signal and generate a digital rotor position signal. The digital rotor position signal forms a time-related data stream which corresponds to the sampled and quantized rotor position signal. The control unit includes an interpolator which is designed to generate at least one intermediate value in the digital rotor position signal, said intermediate value lying between two successive rotor position values.

    • A method for triggering a heterodyne interferometer having two acousto-optical modulators in separate light paths, a receiver generating an analog signal and a downstream A/D converter converting the analog signal into a digital signal is described; in this method, the one acousto-optical modulator is triggered at a modulation frequency f1 and the other acousto-optical modulator is triggered at another modulation frequency f2, the difference between modulation frequencies f1 and f2 forming a heterodyne frequency fHet and the analog signal being converted into the digital signal in the A/D converter at sampling frequency fa. In such a heterodyne interferometer, a fixed ratio of modulation frequencies is maintained, and they are prevented from shifting due to aging and drift by forming at least two of the frequencies of modulation frequencies f1, f2 and sampling frequency fa from a fundamental frequency fquartz of a common oscillator. As a result, it is also possible for sampling frequency fa to be in a fixed phase ratio to the differential frequency of modulation frequencies f1, f2, of heterodyne frequency fHet. Measurement accuracy is increased because sampling is performed at a constant phase, independently of drift and aging.

    • A laser diode (1) of a laser vibrometer emits light which is guided onto a polarization beam splitter (3) by a lens 2. A portion of the beam is guided through directly to an imaging lens (4) and a second portion is deflected onto a mirror (5). Quarter-wave plates (6) and (7) are arranged between the polarization beam splitter and respectively the lens or the mirror. The beam which is reflected on the mirror is guided completely through the polarization beam splitter onto a photodetector unit (8). The beam reflected by the object (9) to be measured, which swings in the direction (14), is also deflected to the photodetector unit. The output signal of the photodetector unit, the interference signal generated from the superposition of the two reflected beams, is supplied to an electronic evaluation equipment (10). The latter is also supplied with a signal of a current modulator (11) which, on the other hand, supplies the laser diode with modulated injection current via line (12). The distance between the imaging lens and the object to be measured forms an optical detour (13) which is considerably lengthened compared to the reference arm.
