摘要： A contactless optical process with which characteristics such as the type, position, deformation, and vibration spectrum, of an object can determined and/or measured. In this process, coherent light is changed by an optical medium fixed to the object. Suitable optical media, such as acousto-optical transducers or special holograms, are selected for the respective characteristics. A photosensitive receiver equipped with evaluation means determines the respective characteristics of the object from the changes in the coherent light caused by these optical media.

摘要： To monitor machines for breakage and/or wear of the tool, the vibrations produced by dynamic forces generated by the machine parts are measured in the range of the natural frequency of the machine above the operating frequencies. The measured values are compared, as the desired states or conditions, with the respective momentary vibration behavior of these measuring locations and frequency ranges (i.e., the actual operating state or condition), and whenever there is a deviation of the actual state from the desired state by a given threshold value, a signal is emitted which may be used to shut down the machine.
