Abstract
The design flexibility of aerospace components has been revolutionized with the recent advancements in the manufacturing of composite structures and 3D printed components. Since the manufacturing process is dependent on the control environment, variations from the nominal conditions can result in the degraded surface quality of the manufactured part. It is critical to image these surface features at high-resolutions to enable process feedback, therefore, improving the overall efficiency and process control. In this context, we develop and demonstrate a structured illumination optical fiber probe with embedded speckles for high-resolution surface feature imaging of 3D printed and composite samples. The improved sectioning capabilities by modifying the structured illumination patterns is validated using a plane mirror sample. This method is envisaged for high-resolution surface feature imaging to improve the overall manufacturing process efficiency of critical components.
