Abstract:
1. A vibrating microtome and a measurement device, comprising: a knife adapted to vibrate in a direction parallel to a section plane and substantially parallel to a cutting edge of the knife; a light barrier oriented in a direction parallel to the section plane and the cutting edge partially covering a light beam of the light barrier; a measured signal (tpm) generated by the light barrier, wherein fluctuation of the measured signal (tpm) indicates the presence of a transverse offset of the cutting edge; at least one control application signal (pklo, pkhi) generated by a control application signal generator, the at least one control application signal (pklo, pkhi) describing a time course of the vibration of the knife; and a microcontroller for receiving the at least one control application signal (pklo, pkhi) and the measured signal (tpm), the microcontroller determining a magnitude of transverse offset based on the measured signal at points in time determined from the at least one control application signal (pklo, pkhi).
