Detection of Defects on Components Real Time Mode Monitor Q-501 The Real Time Mode Monitor Q-501 the real time visualization of vibration modes of har-monically excited objects. Components in R&D and Production Qualitative true full-field Investigation The instrument is best suited for the develop-ment and testing of complex components and structures in acoustics and electronics, auto-motive design, aerospace, machining and re-search. It is ideal for the experimental verifica- tion of analytical and numerical calculation techniques as well as go-no go test in produc-tion. The measurement is performed without contact and allows to visualize the whole area of inter-est simultaneously. This avoids the drawbacks of compiling traditional single point measure-ments or time consuming scanning techniques. Easy Handling No marking or manipulation of surface is re-quired on the measured object. With its unprecedented compactness the sen-sor head offers convenient portability and flexible set-up for instant dynamic measure- ment. >
