We present the development of an interferometer capable of making contactless measurements Adapters of vibrations.The results show the we achieve micro- and/or nano-metric measurements without the stabilization of the laser.While there are multiple techniques to achieve this objective, in this case, Airliner Model Kits we use a method whose main virtue is the low component count and the self-alignment capacity.The method is based on the optical feedback effect in a laser diode which relieson the use of an internal reference for calibration.
