Abstract :
The paper describes our measurement of scattered light for multipoint laser-fiber vibrometry. We use the coherent radiation in the 1550 nm range and we adopted WDM technique for multiwavelength operation. It allows to apply 3-point measurements of vibrating object to establish 3D vibration. This paper describes three fiber-free space configurations in order to establish the best detection conditions.
