Laser interferometric vibrometer

The goal of this project is to make an open source vibrometer that uses a back reflected laser signal from a surface to measure vibration of that surface. The device should measure displacements of objects to the resolution of a half wavelength of light which is 0.0000003 meters. More information shall be given as this progresses along. Updated information shall first be published on the project’s hackaday page http://goo.gl/n6HRXO
