Biomedical optics is a field that combines biology and optical science to study and improve medical diagnostics and treatments. It uses light-based technologies to visualize biological tissues, enabling researchers and clinicians to observe cellular structures and functions in real-time. Techniques in biomedical optics include optical coherence tomography (OCT) and fluorescence imaging, which help in detecting diseases like cancer and monitoring tissue health. By harnessing the properties of light, biomedical optics plays a crucial role in advancing medical research and enhancing patient care through non-invasive methods.
