    Perspectives of optical coherence tomography imaging and Raman spectroscopy in cancer diagnosis

    Biomedical optical imaging and optical spectroscopy are rapidly emerging as strong contenders for non-invasive optical biopsy. In biomedical imaging, Optical Coherence Tomography (OCT) is an established imaging modality for non-contact depth-resolved three-dimensional imaging with micrometer scale resolution. OCT provides label-free micro-structural morphological information of the tissue. Raman spectroscopy is a complementary tool for obtaining molecular-specific information for diagnosis. This article provides a brief overview of the underlying principles of OCT and Raman spectroscopy, their instrumentation with representative latest developments in cancer diagnosis.
