- W118328663 abstract "As part of the Lisa Technology Package (LTP) on board the LISA-PATHFINDER spacecraft, the LISAPATHFINDER interferometer is of the heterodyne MachZehnder type. It requires as input two light beams derived from the same source but with a small frequency difference (a few kHz). These two optical beams are produced in the Laser Assembly (LA) via the Laser Modulation Unit (LMU). The LMU includes an optical bench, two Acousto-Optic Modulators and two Optical Delay Lines [1]. The optical configuration was desi gned by Oerlikon Space AG. The optical delay line is bas ed on a triple prism, whose position is actuated by an am plified piezo actuator (Optical Path Difference Actuator OPDA), which was designed and qualified by CEDRAT TECHNOLOGIES SA. The OPDA has a stroke of 60 µm, and a bandwidth of 10 Hz. In order to reduce parasitic rotation effects, an e lastic guided stage was designed: to save mass, the piezo actuator and the stage supporting the triple prism were machined out of Titanium alloy as a single part. FE M simulations were used extensively to optimise the O PDA design with respect to its functional specification s, its behavior under random vibrations and its thermomechanical deformations. The design also took into consideration the thermal mismatch between the OPDA and the optical bench which is made with Aluminium alloy." @default.
