Bachelor's Thesis

Ellipsometric Investigations on the Ouzo-Effect

Although multiple scattered light is a daily life experience (white walls, milk), in the microscopic description of strongly scattering samples there a lot of open questions. A nice example, which came into the scientific view during the last years, is the Ouzo-effect. Mixing Ouzo, a composite of Anis oil in alcohol, with water gives a milky solution.

In the Bachelor thesis it is planned to characterized Ouzo-water mixtures with ellipsometry over a larger wavelength range. A deeper analysis of the so obtained Mueller matrices then allows to reveal the underlying physical processes of depolarization. By varying the water concentration, the number and size of the scatterers in the emulsion can be tuned.

In the framework of the thesis you can gain first scientific experiences on a basic optical problem with a strong connection to daily life.
