Laser-self-mixing interferometry for mechatronics applications.

Ottonelli S, Dabbicco M, De Lucia F, di Vietro M, Scamarcio G - Sensors (Basel) (2009)

Bottom Line: We report on the development of an all-interferometric optomechatronic sensor for the detection of multi-degrees-of-freedom displacements of a remote target.The prototype system exploits the self-mixing technique and consists only of a laser head, equipped with six laser sources, and a suitably designed reflective target.The feasibility of the system was validated experimentally for both single or multi-degrees-of-freedom measurements, thus demonstrating a simple and inexpensive alternative to costly and bulky existing systems.

Mentions: The prototype of the sensor, illustrated in Figure 9 (a), is similar to that previously described in Figure 6. The only difference consists in the target configuration, which is given by three reciprocally tilted mirrors [Figure 9(b)]: M1 is a squared mirror of side 20 mm lying in the plane yz, M2 is a rectangular mirror of dimension 50 mm × 20 mm, tilted at angle α = (2.1 ± 0.1)° around the z – axis, M3 is a rectangular mirror (70 mm × 50 mm) tilted at angle β = (1.8 ± 0.1)° around the y - axis.
