Polarization difference ghost imaging
Applied Optics, 2015We propose the polarization difference ghost imaging method and experimentally demonstrate that polarization properties can provide additional information in conventional ghost imaging for object discrimination with contrast enhancement. In our experiment, two kinds of visually similar objects with different polarization properties can be separated for

Biologically Inspired Polarization-difference Imaging
27th European Microwave Conference and Exhibition, 1997Without appropriate instruments, human eyes cannot effectively sense the polarization of light. However, it is well known that the eyes of certain animal species are sensitive to light's polarization. Motivated and inspired by hypotheses about the polarization sensitivity of the visual systems of such animals, our research group has been studying and ...

Polarization analysis and corrections of different telescopes in polarization lidar
Applied Optics, 2015Telescopes in polarization lidar often modify the input polarization of the return signal, such that the telescope may significantly impact the depolarization estimates of aerosol and introduce error to the polarization lidar measurements. The error cannot be corrected by a traditional calibration constant.

Optimal configurations for different incident polarization states in linear polarization calibration
Applied Optics, 2020The purpose of polarization calibration is to measure the response matrix of an instrument and the deviation of noise to correct for subsequent flight measurements. The precision, however, is relative to the states of incident light. We investigate the influence of partially polarized light, in the presence of signal-independent additive noise or ...

Statistical Difference Beyond the Polarizing Regime
2019The polarization lemma for statistical distance (\({\text {SD}}\)), due to Sahai and Vadhan (JACM, 2003), is an efficient transformation taking as input a pair of circuits \((C_0,C_1)\) and an integer k and outputting a new pair of circuits \((D_0,D_1)\) such that if \({\text {SD}}(C_0,C_1) \ge \alpha \) then \({\text {SD}}(D_0,D_1) \ge 1-2^{-k}\) and ...

Polarization characteristics of He–Ne laser with different directions of polarized feedback
Applied Optics, 2013A polarizer is placed in an external feedback cavity to form polarized optical feedback. The effect of the different directions of polarized optical feedback on laser polarization characteristics (LPCs) is investigated experimentally and theoretically. The angle between the optical axis of the polarizer and the laser polarization is changed from 0° to ...

Microemulsion Formation with Chlorinated Hydrocarbons of Differing Polarity
Environmental Science & Technology, 1994Winsor Type I, Type II, and Type III (middle phase) microemulsions have been produced for water and CCl 4 , water and trichloroethylene (TCE), and water and 1,2-dichlorobenzene (DCB) with anionic surfactants and appropriate electrolytes. Attempts at producing classical phase behavior with several more polar chlorinated hydrocarbons were unsuccessful ...

The binding of drugs to different polar lipids in vitro
Biochemical Pharmacology, 1979Abstract For evaluation of the physico-chemical basis underlying the drug-induced generalized lipid storage disease, the equilibrium distribution of radioactively labelled amphiphilic drugs between a water phase and liposomes was determined. Liposomes were prepared from sphingomyelin (SM), phosphatidylcholine (PC), phosphatidylethanolamine (PE), and ...
