Spectral-polarizing beam splitter for simultaneous polarimetric imaging in a common IFOV
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.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
