Biomedical optics combines the principles of physics, engineering, and biology to study the interaction of biological tissue and light, and how this can be exploited for sensing, imaging, and treatment.<ref>{{Cite web |url=https://www.ucl.ac.uk/medphys/contacts/people/bcox/MPHYX910_Biomedical_Optics_notes_Nov2015.pdf |title=Introduction to Biomedical Optics |access-date=2018-01-25 |archive-date=2024-07-26 |archive-url=https://web.archive.org/web/20240726171612/https://www.ucl.ac.uk/medphys/contacts/people/bcox/MPHYX910_Biomedical_Optics_notes_Nov2015.pdf |url-status=live }}</ref> It has a wide range of applications, including optical imaging, microscopy, ophthalmoscopy, spectroscopy, and therapy. Examples of biomedical optics techniques and technologies include ''[[optical coherence tomography]]'' (OCT), ''[[fluorescence microscopy]]'', ''[[confocal microscopy]]'', and ''[[photodynamic therapy]]'' (PDT). OCT, for example, uses light to create high-resolution, three-dimensional images of internal structures, such as the ''[[retina]]'' in the eye or the ''[[coronary arteries]]'' in the heart. Fluorescence microscopy involves labeling specific molecules with fluorescent dyes and visualizing them using light, providing insights into biological processes and disease mechanisms. More recently, ''[[adaptive optics]]'' is helping imaging by correcting aberrations in biological tissue, enabling higher resolution imaging and improved accuracy in procedures such as laser surgery and retinal imaging.
