A novel delay line for time domain optical coherence tomography (OCT) is demonstrated optically. The measured devices, which are based on the thermo-optic effect of silicon, are able to reach line acquisition speeds in excess of 10 kHz and produce a scan of 410 mum in air. Attention is drawn to the effect of group velocity dispersion originating in the material properties of silicon on system resolution,...
Little is known about the information that can be gained optically about clinically relevant properties of osseous tissue. However, optical methods have the potential to recover rich information about bone condition around skeletal implants in-vivo. In this paper this potential was investigated by relating time-resolved optical measurements on 15 excised samples of trabecular bone to corresponding...
Vertebral arthrodesis supported by cage devices is a successful surgical option for treating degenerative disorders of the spine. Despite the favourable results reported, the process of formation and maintenance of bone tissue is not well understood. Improving knowledge on these multifactorial biological mechanisms is crucial to advance the technique. Diffuse optical tomography (DOT), implemented...
