Laser diode self-mixing: Range-finding and sub-micron vibration measurement

A plain laser diode can easily measure sub-micron vibrations from centimeters away by self-mixing interferometry!  I also show how this technique can be used for range-finding.

  1. Hi Ben,

    Very nice videos. You can do a full video on making a tunable external cavity diode laser. It would be quite useful.
