thermal expansion, optical mount
Abstract:
In this presentation we will discuss a method for determining a point whose position is invariant under thermal expansion for an optical mount used for the CAS system on the ESA LISA mission satellites and we will analyze the displacement distributions for various geometries of the baseplate that supports the optical mount.
