Lightweight, Stable Optical Bench with Integrated Vibration Attenuation

The goal of this program is to design a lightweight optical bench capable of remaining stable under temperature and moisture changes, while isolating the precision optical array from vibrations such as engine noise and air turbulence. By integrating a customizable periodic stack in the bench, vibrations are attenuated more effectively than commercially available mounts. Additionally, the periodic stack allows for a decrease in overall bench stiffness, reducing weight, envelope, and flight cost. During this project, San Diego Composites and Boston University will develop a light weight flight-ready optical bench with integrated vibration damping properties that is insensitive to temperature and moisture changes. SDC plans to meet the goals of this project by utilizing our extensive design and analysis knowledge, advanced composite manufacturing techniques, and highly detailed testing experience.
