Abstract
A new, to the best of our knowledge, multi-purpose spectral-polarizing beam splitter (SPBS) design is described that simultaneously isolates multiple identical reflected and transmitted polarized passbands to permit passive simultaneous polarimetry in a common instantaneous field of view (FOV). The SPBS design can be implemented in wavelength regions between ∼260nm and ∼1700nm and consists of fewer than 30 layers. Degree of linear polarization values are ∼0.99. FOV area coverage in a swath as wide as 6° is accomplished by object space scanning. A polarization calibrator/stability monitor source is integrated with the optical system. Estimated system polarimetric error is <2%. Applications range from biomedical instrumentation to remote sensing.
