Initial Results and Field Applications of a Polarization Imaging Camera

摘要

The SALSA linear Stokes polarization camera from Bossa Nova Technologies (520-550 nm) uses an electronically rotated polarization filter to measure four states of polarization nearly simultaneously. Some initial imagery results are presented. Preliminary analysis results indicate that the intensity and degree of linear polarization (DOLP) information can be used for image classification purposes. The DOLP images also show that the camera has a good ability to distinguish asphalt patches of different ages. These positive results and the relative simplicity of the camera system show the camera's potential for field applications.
