Quantification of Standing Wave Patterns in Rotating Flexible Disks Using Optical Reflection Techniques

Abstract

This paper is a follow-on to a paper previously presented to ASME on an experimental instrument designed to enable the observation of standing wave modes for flexible media. In that earlier paper qualitative results showing changes in the disk standing waves were obtained using the experimental setup. The current paper presents the same experimental system from the perspective of looking at the system as an optical instrument, and, based on optical ray trace methodology, quantifies the results seen in the previous paper on a more absolute basis. Based on this analysis, the authors also describe design changes from both an instrument setup perspective and the application of other electro-optic sensor technologies which will improve the system’s static and dynamic resolution.
