A spectrometric device for optical analysis of material composition, coating thickness, surface porosity, and/or other characteristics uses several monochromatic light sources&#x2014;e.g., laser diodes&#x2014;to illuminate a sample, with a camera taking an image of the sample under each source's light, and with the various images then being combined to generate a (hyper)spectral image. To address the difficulty in obtaining uniform illumination intensity across the illuminated sample area with solid-state light sources, the output from the light sources may be supplied to an integrating sphere (preferably after being combined within a fiber combiner), and then to a fiber bundle whose output ends are configured as a ring light (a ring of fiber ends directing light at a common spot). The camera may then focus on the spot, at which the sample may be placed for illumination and imaging.

Spectral imaging with multiple illumination sources

A method and apparatus for inspecting a composite structure. A resin inspection system comprises a housing having an open section, a movement system associated with the housing, a light source associated with the housing, an infrared measurement system associated with the interior of the housing, and a visible light sensor system. The movement system is configured to move the housing on a surface of a composite structure. The light source is configured to emit light. The infrared measurement system is configured to generate infrared measurement information from infrared light detected by the infrared measurement system through the open section. The visible light sensor system is configured to generate image information about the surface of the composite structure.
