Paper Abstract

A simple, non-intrusive technique to separate mechanical jitter and aero-optic jitter from the combined measured jitter is presented. This technique has the advantages of being relatively simple to implement, deriving information from the imaging data, and giving insight into the nature of the flow field turbulence. This method employs variable collection apertures and a subtraction algorithm designed to separate aero-optic jitter from mechanical jitter. Several levels of vibration and aero-optic effects were measured and then separated in the post-test data processing.
