Stroboscopic Inline Coherent Imaging
Inline coherent imaging (ICI) is an in-situ monitoring technique, used in laser processing applications such as welding and additive manufacturing. Conventional ICI systems image with a continuous-wave broadband light source, which makes the system susceptible to an effect known as motion artifact. …

Inline Coherent Imaging of Laser Additive Manufacturing
… In this thesis a low-coherence interferometric imaging technique, termed inline coherent imaging (ICI), is integrated into the selective laser melting process to monitor melt pool morphology changes and stability at 200 kHz with axial and transverse resolutions reaching 6 µm and 35 µm …

Monitoring Material Modification using Inline Coherent Imaging
… in situ metrology is required. In this work, a coherent imaging technique analogous to spectral domain optical coherence tomography (SD-OCT) was applied inline with a machining laser in order to monitor the cut development of various materials for industrial and biomedical applications. Such …

Ablation of Steel by Microsecond Pulse Trains
… morphology changes to melt and vapour ejection. Inline coherent imaging (ICI), a broadband, spatially-coherent imaging technique, is used to monitor the ablation process. The pulse parameter space is explored and the key regimes are determined. Material removal is observed when the pulse delay is …

Highly Efficient Thermal Ablation of Silicon and Ablation in Other Materials
… cost. The work here shows that by combining an imaging technique frequently used in ophthalmology called optical coherence tomography (OCT) with a machining platform, in situ observation of ablation can be made. This combination, known as in-line coherent imaging (ICI), allows information to be …
