1. Improved inspection and micrometrology of embedded structures in multi-layered ceramics : Development of optical coherence tomographic methods and tools
Abstract : Roll-to-roll manufacturing of micro components based on advanced printing, structuring and lamination of ceramic tapes is rapidly progressing. This large-scale and cost-effective manufacturing process of ceramic micro devices is however prone to hide defects within the visually opaque tape stacks. READ MORE

2. Assessment of optical coherence tomography for metrology applications in high-scattering ceramic materials
Abstract : Large-scale and cost-effective manufacturing of ceramic micro devices based on tape stacking requires the development of inspection systems to perform high-resolution in-process quality control of embedded manufactured cavities, metal structures and defects.In this work, alumina ceramic samples are evaluated by optical coherence tomography (OCT) operating at 1.

3. Laser spectroscopic analysis of atmospheric gases in scattering media
Abstract : Laser spectroscopic techniques for gas analysis under various influences of light scattering are explored in a wide spectral range from the ultraviolet to the infrared. The techniques rely on spectrally narrow-band light sources that are used in differential optical absorption measurements. READ MORE
