AMI
AMI builds Chameleon, a terahertz-based measurement platform for non-contact, non-destructive inspection of coating thickness, multilayer structures, corrosion, and composite defects. The system coordinates a motorized 3D stage, terahertz signal processing, and analysis software into a single workflow, delivering thickness values, layer breakdowns, or 2D maps. Chameleon can image subsurface corrosion creep along ISO 12944 scribes without removing the coating.

Problem
Traditional coating thickness gauges require physical contact that can compress soft materials or damage critical surfaces, and they collapse multilayer stacks into a single number. Corrosion evaluation under coatings typically demands destructive removal of the coating, and internal composite defects like wrinkles and delaminations sit beyond the reach of visible inspection and standard ultrasound. These limitations force teams to choose between destructive testing, unreliable readings, or delayed detection.
Solution
AMI offers Chameleon, a terahertz-based measurement platform that provides non-contact, non-destructive inspection of coating thickness, multilayer structures, corrosion, and composite defects. The system uses reflected terahertz light to resolve individual layer thicknesses within a multilayer stack from a single measurement, eliminating the need for cross-sectioning. Chameleon coordinates a motorized 3D stage, terahertz signal processing, and analysis software into one workflow, allowing operators to place a sample, define a scan pattern, and immediately obtain thickness values, layer breakdowns, or 2D maps. For corrosion testing, Chameleon images subsurface corrosion creep along ISO 12944 scribes without removing the coating, enabling repeat measurement of the same coupon over time. In composite work with Siemens Gamesa, the platform detected wrinkles in wind blade layups non-destructively, resolving the location and depth of internal features.
Target Audience
Primary users are materials testing teams, coatings manufacturers, corrosion testing laboratories, and composite manufacturers — including organizations such as wind blade producers — who need reliable, non-destructive measurement of coating thickness, multilayer builds, corrosion progression, or internal structural defects.
Features
- Terahertz light-based measurement for non-contact, non-destructive inspection on all substrate types, not just metallic ones
- Per-layer thickness retrieval from a single measurement, verifying layer order and stack integrity without sectioning
- 2D corrosion mapping beneath intact coatings with extractable affected areas measurable against ISO 12944 creep criteria
- Internal defect imaging in composites, resolving fibre wrinkles and ply separations through the layup
- Motorized 3D stage with ~20×20×10 mm travel, extendable or shortened, paired with custom-shaped sample holders
- Unified software interface for scan configuration, live result visualization, and analysis, with point, line, and plane scan patterns
- Exportable outputs in PDF format for human review and CSV format for machine-readable pipelines
