Method and apparatus for two-dimensional vibration analysis

摘要

A method and an apparatus are provided for contact-free optical displacement and/or vibration measurement of an object, in which the object to be measured is scanned in the form of a grid. The position of the measurement points and the contour of the grid are freely selectable. Individual measurement point subquantities, to be analyzed respectively in correlation with one another, can be classified in different categories and analyzed as a function of the category to which they are assigned.
