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.
