A single-input and single-output (SISO) frequency modulated continuous wave (FMCW) radar architecture is proposed and in vivo demonstrated for remote 2-D localization (range and angular information) and vital signs monitoring of multiple subjects. The radar sensor integrates two frequency scanning antennas which allow angular separation and enable determining a 2-D map (range versus angle) of a room environment from which people can be distinguished from objects and clutter.

Biological structures such as wood fibers or tissue cells often have a characteristic alignment of their molecular
architecture. Therefore cells, tissues, organelles can show birefringence and dichroism with the passage of light,
which can be detected and measured accurately by performing polarized light imaging. This technique allows to
highlight both micro- and nano-structures of the materials, characterizing the anisotropy of the optical properties
