Abstract

Due to the unprecedented increase in telework requirements, the motivation to further automate and remotely control experiments has become apparent. This work documents the technical development of creating a two-dimensional (2D) Laser Doppler Vibrometry (LDV)measurement using a single-point LDV system through an automated and remotely controllable process. This report aims to assist in rapid development of setups for similar use cases. The setup described is also modular, and has been used to analyze the modal response of samples actuated through air-based acoustic signals as well as those mechanically induced.
