Abstract
This paper presents a simple, nonintrusive technique to separate mechanical jitter and aero-optic jitter from the combined measured jitter. 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. The 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 posttest data processing.
