Removing Mid-Spatial Frequency Errors with VIBE, Phase II

Completed Technology Project

Project Introduction

Removing Mid-Spatial Frequency Errors with VIBE, Phase II
The Optimax VIBE finishing process is a fast (<60 second), full-aperture, conformal polishing process incorporating high frequency motion that rapidly eliminates mid-spatial frequency (MSF) errors created by deterministic polishing. During Phase I, we were able to show feasibility that the Optimax VIBE finishing process was able to reduce the effects of mid-spatial frequency (MSF) errors on flat sub-aperture polished surfaces without negatively affecting the surface figure. With future funding, we anticipate advances this process will result in a cost-effective way to produce ultra-low MSF error curved surfaces for both NASA and non-NASA applications. More »
