Polarization cameras

Samba

Samba is a polarization camera that allows to determine the level of polarization for each pixel very quickly.

Functional Principle

The polarization camera Samba is mainly used in an image configuration where the scene is illuminated by a known source. The best results are obtained with full polarized illumination of the specimen.

Salsa

Salsa is a polarization digital camera that determines the full Stokes vector (S0 to S3) for each pixel.

Functional Principle

Conventional polarization imaging systems are implemented with mechanical rotation of polarizers and waveplates. These systems are usually relatively slow and very sensitive to the movement of the scene between images.
A patented polarization filter based on ferroelectric liquid crystals (FLC) is used, which drastically reduces the time required to acquire a complete polarization image consisting of four individual images. The Stokes vector is then calculated for each pixel from these four individual images.

Both cameras are compact and robust and have all the features of a conventional digital video camera (simple operation, point & shoot, USB3 connection) as well as the possibility of polarization analysis.
