Learners enrolled: 944

Learning objectives:
The key objectives of this course are to:

▪ Detailed understanding on optics fundamentals, light-tissue interaction, molecular spectroscopy.

▪ Understand phenomena such as scattering, absorption, fluorescence, and polarization, and how these properties can be utilized in biomedical diagnostics and imaging.

▪ Learn photon transport equation in turbid media, diffusion theory approximation, and Monte Carlo methods for solving inverse problems. Different configurations of near-infrared spectroscopy, such as continuous wave, frequency domain, and time-domain.

▪ Provide hands-on experience in optical instrumentation and characterization of optical tissue phantom that mimics optical properties of biological tissues.

Learning outcomes:

On successful completion of the course, the student will be able to:

▪ Acquire fundamental understanding of the optical instruments (optical components, source, and detectors).

▪ Analyze the underlying mathematical model of the light-tissue interaction and the optical techniques to quantify tissue physiological attributes.
