We present novel applications of Bossa Nova Technologies Linear Stokes polarization camera. The SALSA camera is able to perform live measurement of Linear Stokes parameters, usual polarization parameters (Degree Of Linear Polarization and Angle Of Polarization) and other polarization based parameters (polarized image, depolarized image, virtual polarizer, polarization difference). First a brief description of the SALSA camera and its calibration is given. Then we present and discuss several results of target detection and contrast enhancement experiments. We will also introduce a novel polarization based metrological method of 3D shape measurement for in-line control of optical surfaces and control of highly aspheric optical surfaces. The architecture of the hardware and calibration results is presented. A new algorithm based on polarization imaging leading to the construction of the gradient field is described. Finally experimental results and observations as well as possible further steps are discussed.
