Dr Shreevathsa Chalathadka Subrahmanya (University of Hamburg)

One of the key components of the payload of the Lunar Gravitational-Wave Antenna is the inertial sensor, which measures the differential motion between the lunar surface and the inertial mass. To detect gravitational waves, the inertial mass motion must be read out with sub-femtometer precision.

In this talk, I introduce a laser interferometric displacement sensing scheme called heterodyne...
