Key Variables For Contrast Sensitivity

Wes Wren

Sales Manager

There are a number of variables that contribute to improved contrast sensitivity in a sample:1. FACTOR: SAMPLE THICKNESS- Sample thickness is a vital part in determining what the contrast sensitivity will be. When acquiring two data sets of the same material, and scanning them at the same resolutions, it is clear that the thinner sample shows better contrast sensitivity on a similar void then the thicker sample. 2. FACTOR: MATERIAL DENSITY- Density of material is a key factor in determining whether the contrast…

NSI Technology Used for Composites Analysis

Julien Noel

General Manager – NSI Europe

Composite is a very popular material for many different applications, such as Aerospace, Automotive, and Structural constructions. It is usually lighter, stronger, and in most cases less expensive than traditional material. A good example is the Boeing 787 Dreamliner which is the first passenger airplane to use composite materials as the primary material in the construction of its airframe.The tricky part with composite is the inspection. The structure is so complex – usually Fiber-reinforced polymers, or carbon-fiber reinforced plastic, or glass-reinforced carbon, etc – that it makes it difficult to inspect…

7 Frequently Asked Questions about CT Scanning

Ben Connors

Inspection Services Manager

 1.       Can I scan my part? To answer this we need to ensure we are focused and optimized in the right areas by digging deeper in to the goals of the project.  First, we review the physical size of the sample, because smaller samples and more localized areas of interest will yield higher resolution data sets. Systems can be as small as desktop and as large as a walk in vault, each with its own capability…
