Raman Spectroscopy and Optical Coherence Tomography on a Chip

چکیده
Miniaturization of optical instruments for biomedical applications requires the development of efficient means to deliver excitation light to – and collect the resulting signals from – biomedical tissue by an optical microchip, as well as spectral analysis of the acquired information on the chip. We have investigated light collection by integrated waveguides, invented a method for on-chip confocal light delivery and collection, proposed new designs and developed high-resolution arrayedwaveguide gratings (AWGs), and demonstrated Raman spectroscopy and spectral-domain optical coherence tomography (OCT) on a chip.

Integrated AWG Spectrometer for On-chip Optical Coherence Tomography and Raman Spectroscopy
Silicon oxynitride-based arrayed waveguide grating (AWG) spectrometers were designed for on-chip spectral-domain optical coherence tomography (OCT) systems and Raman spectroscopy of the skin. A novel geometrical layout for Raman spectroscopy was introduced to reduce loss. Measurements show that integrated optics has a good potential for miniaturizing current OCT systems. Keywords-arrayed wavegu...
متن کاملCombined Information from Raman Spectroscopy and Optical Coherence Tomography for Enhanced Diagnostic Accuracy in Tissue Discrimination
Optical spectroscopy and imaging methods have proved to have potential to discriminate between normal and abnormal tissue types through minimally invasive procedures. Raman spectroscopy and Optical Coherence Tomography (OCT) provides chemical and morphological information of tissues respectively, which are complementary to each other. When used individually they might not be able to obtain high...
متن کاملIntegrated system for combined Raman spectroscopy-spectral domain optical coherence tomography.
Raman spectroscopy (RS) and optical coherence tomography (OCT) are powerful tools for optical analysis of tissues with mutually complementary strengths and limitations. OCT excels at visualizing tissue microstructure but lacks molecular specificity, while RS can relay tissue biochemical composition but typically cannot relate microstructure. Previous implementations of combined RS-OCT have util...

متن کاملClinical Applications of Optical Coherence Tomography in Ophthalmology
Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases. Furtherm...
