Biomedical and Biosensing Optical Devices


The course deals with the structure and principles of operation of a variety of optical instruments for medical diagnosis and optical sensors for analytes detection. It can be divided into three main parts:
a. Optical biosensors: basic optical principles used for optical biosensing such as: absorption, TIR, surface waves such as SPR, waveguides and fibers, interferometry, ellipsometry, spectroscopy (fluorescence, Raman) and discussion of biosensors properties based on these phenomena. Examples of existing sensors for the medical applications.
b. Optical properties of tissue: propagation models in tissue, scattering, absorption, change of polarization, structure of the eye and its optical properties, introduction to eye optics and vision. Interaction of lasers-tissue and lasers applications in surgery, wound healing, hair and tattoo removal, dental treatment, and vision correction. Blood oximetry will be discussed in detail as well as the search for non-invasive glucose monitoring device, bilirubin level monitoring in blood.
c. Medical optical imaging methods: Optical microscopy (standard, dark field, dark field, polarized, confocal, fluorescence, interferometric), optical coherence tomography (OCT), photo-acoustic tomography, Doppler tomography, polarimetric and spectral imaging. Examples for cancer diagnosis with optical imaging methods, modern optical microscopy techniques exhibiting superresolution.
d. Biomedical optical devices: Oxymeters, optical glucometers, lasers in surgery, laser Doppler, cosmetics, hair and tattoo removal, classical ophthalmic instruments such as slit lamp, fundus camera, tychometer, eye aberration measurement devices, eye laser corrections, OCT.
