Abstract
The SALSA camera from Bossa Nova Technologies uses an electronically rotated polarization filter to measure four states of polarization nearly simultaneously. Initial imagery results are presented, with an investigation of polarization invariants, as affected by illumination, sensing geometry, and atmospheric effects. Applications for the system as it is being developed are in change detection and surface characterization. Preliminary results indicate an ability to distinguish new from old asphalt and disturbed earth from undisturbed earth with some image processing.
