ROMY: Rotational Motions in Seismology
by Jonas Igel
ROMY is a rotational motion sensor at the LMU Munich. Its technology is based on the Sagnac effect where two lasers are sent in opposite directions and the phase shift is measured which correlates to ground rotation. With its four rings, ROMY is the most sophisticated ring laser in the world at the moment. Visible here is the point where three of those rings meet.
