Abstract :
In this paper, the authors describe the design and
the experimentation of a polarimeter aimed at characterizing
the properties of some scattering materials (e.g., a scattering
liquid containing a foreign body, or skin components, such as
collagen). The polarimeter presents the advantage of offering an
easy understanding of Stokes and Mueller formalism. Thus, it is
typically suited for university students in physics (Master’s level),
giving them a clear understanding of polarization and birefringence.
Another application is possible in schools of engineering,
where students may use their design abilities to improve the
apparatus performance. Apparatus automation was performed
as well, providing easier use for experiment (commodity of use,
reproducibility, and possible multiplication of measurements).
The apparatus was tested in transillumination and backscattering
modes. More generally, measurements can be performed with
angles varying from 0 to 150 between the propagation direction
and the line from the sensor to the sample material. In addition,
the sensor can be either a photodiode (results presented here)
or a two-dimensional (2-D) sensor charge-coupled device (CCD)
camera. As an application, the apparatus was used to differentiate
irradiated and nonirradiated collagen.
