Composites materials are well-suited to measurement by 4D InSpec. The surface inspection gauge uses a projected light technique that isn’t affected by color, and readily measures textured and rough surfaces, even material changes in the same field of view. 

Nose cones, which need to be permeable and transparent to sensors and signals, are made from materials like fiberglass, quartz, fiber composites, even foam. They’re notoriously hard to image, because their absorptive colors and texture are challenging. 4D InSpec can easily image scratches, nicks, seals, pockets and countersinks, mounting holes and flanges on composites.

By using the analysis software, you can use powerful analysis techniques—like cylinder shape removal—which help you properly assess scratches, pits and wear. Take a look at the tutorial video below!

Because the measurement is a 3D area, you can place a profile trace anywhere across the feature, and not worry about having lined up the gauge before measuring.
