Curricular information is subject to change.

This course will introduce students to the field of optical spectroscopy. Optical spectroscopy provides information about the external world through measurement of the interactions between materials and light. This enables non-destructive measurement of quality in a wide range of agri-food, pharmaceutical and material science domains.

In this module, students will learn how to become critically aware of the basic principles, practice and applications of optical spectroscopic sensors. The underlying theory of ultraviolet, visible, near infrared, mid-infrared and Raman spectroscopy will be explored and illuminated through several real world examples. Standard approaches and configurations for acquisition and analysis of spectral and spatial data will be covered both in lecture and lab sessions. Spectroscopic data analysis tools such as Principal components analysis for will be implemented through tutorial sessions.

Students will participate in lectures, through group work in tutorials and laboratory work, where they will select and evaluate an application in optical spectroscopy. Participants will also be provided with spectroscopic data to explore in class.
