Sensors to quantify movements

I'm currently involved in an experimental project that requires quantifying the movement of an object (1 cm x 1 cm) buried in a gravel box. The measurement accuracy has to be around 2-3 mm and frequency around 0.1 Hz. I'm pretty sure that this is comparatively very primitive sensor, but the issue is to find the right commercial product and the reasonable sensor size.
