Optical Performance as a Function Dynamic Mechanical Loading

摘要

Mechanical vibrations have a large impact on the optical performance of many systems. In order to accurately predict optical performance, an integrated optomechanical analysis is required. It is difficult to pass finite element vibration data to optical programs since harmonic response includes phase angles due to damping, and random response has lost all phase information. This paper discusses a new technique to decompose harmonic and random response into pointing, focus, and wavefront error components in an efficient manner. This technique is compatible with commonly used error budgets. A method to identify key contributors to each error component is also presented.
