Rotating orthogonal polarization imaging
Optics Letters, 2008Surface reflections often present a problem in the polarization difference imaging of tissue. The technique described involves illumination in a single polarization state and detection in the orthogonal polarization state. Synchronously rotating both the illumination and orthogonal detection states provides an image free from surface reflections that ...

Polarizer-free polarization contrast compressive imaging
Imaging and Applied Optics 2019 (COSI, IS, MATH, pcAOP), 2019We extend the single-pixel camera concept to enable polarization contrast compressive imaging without polarizer, from simultaneous detection of light reflected by a Digital Micromirror Device on two photodetectors, and using optimized bivariate signal reconstruction algorithms.

The purpose of active imaging system is to provide discrimination at long ranges independently from the surrounding illumination by using and controlling its own light source. Parameters such as the Doppler shift for coherent devices, the range, or the intensity of the light back scattered by objects have already been used to encode images.

Radioholographic polarized imaging
2005 15th International Crimean Conference Microwave & Telecommunication Technology, 2005The paper is devoted to the identification and localization of target, shielded by the optically opaque media, with the help of polarization radio-holographic imaging. The main goal is to test the ability of acquiring images for each of the orthogonal polarizations separately and comparing the visual identification of the polarization and classic radio-

Polarization diversity imaging
Technical Digest. Summaries of Papers Presented at the Conference on Lasers and Electro-Optics. Conference Edition. 1998 Technical Digest Series, Vol.6 (IEEE Cat. No.98CH36178), 1998We present the potential advantages of using combined imaging systems involving a passive polarimetric thermal imager and a polarimetric laser imager.

The phenomenon of double refraction, which produces polarized light, was discovered in calcite crystals now known as Iceland spar; although we don’t know who first noticed this phenomenon, its description was first published in 1669 by the Danish physician and scientist Rasmus Bartholin (Goldstein, 2011). Bartholin described that objects viewed through

Polarization information for terahertz imaging
2008 33rd International Conference on Infrared, Millimeter and Terahertz Waves, 2008A method to analyze the change in the polarization state of a terahertz (THz) wave by using a typical electro-optic sampling setup with a ?110? zinc-blende crystal as a sensor is presented. To illustrate knowledge of the polarization of the THz pulse, the THz detection function in a ZnTe crystal is presented.

Clustering of polarization-encoded images
Applied Optics, 2004Polarization-encoded imaging consists of the distributed measurements of polarization parameters for each pixel of an image. We address clustering of multidimensional polarization-encoded images. The spatial coherence of polarization information is considered.

Differential Polarization Imaging
1988The development of the differential polarization microscope has allowed us to study a large variety of important biological samples in a way never possible before. This type of microscopy has allowed us to use the different interactions of polarized light with the long range packing of chromophores as a contrast mechanism.

Polarization imaging model considering the non-ideality of polarizers
Applied Optics, 2020Common polarization imaging models are mostly based on an ideal polarizer assumption. This paper proposes a polarization imaging non-ideal model considering the non-ideality of polarizers. The corresponding correction formulas for degree of linear polarization (DoLP) and angle of polarization are also provided.
