Thermo-mechanical-optical coupling within a digital twin development for automotive LiDAR

In this work, the steps of the development of a reduced complexity model (RCM) of a light detection and ranging (LiDAR) system and the requirements for the preparation of a digital twin (DT) from such system are discussed. Preliminary thermal and optical simulations are presented, along with different concepts for cooling of the system. Additionally, current barriers of the direct coupling of thermo-mechanical and optical simulations performed in Ansys Mechanical and Zemax OpticStudio, respectively are discussed.
