چکیده
Imaging through scattering media, such as clouds, biological tissues, and seawater, has broad application prospects in transportation, medical diagnosis, information technology. Researchers have proposed various techniques to obtain images from scattered light passing the among which speckle correlation imaging developed rapidly. Speckle requires non-coherent sources due requirement of memory effect. This makes device complex, source utilization rate low. Additionally, this method is limited its under illumination spatially coherent sources. paper proposes a new based on light, achieved by multiplexing different polarization direction patterns, called imaging. To achieve decoherence source, previous approaches used rotating medium generate time-varying patterns that are integrated over shutter time camera eliminate noise, or multiplexed wavelength-dependent this. uses incoherent polarizers placed path. These superimposed averaged, phase recovery algorithm reconstruct object image. experiment Ping-Pang (PP) with fusion error reduction hybrid input-output targets quickly high quality. The comparison reconstruction results numbers reused demonstrates using more can better image Compared conventional technology, reduces requirements sources, improves simpler compact. Experimental show feasible strong environmental adaptability, expand scope methods.

متن کاملPolarization in Scattering
All the information available from an electromagnetic wave is contained in three variables, direction, wavelength and polarization. This is sufficient to completely characterize light. If you can’t extract the information you want using these parameters, then you have reached the limit of what Electro-Optics can do for you. Historically, optical oceanography has focused on using and analyzing c...
متن کاملHigh-speed polarization sensitive optical frequency domain imaging with frequency multiplexing.
Polarization sensitive optical coherence tomography (PS-OCT) provides a cross-sectional image of birefringence in biological samples that is complementary in many applications to the standard reflectance-based image. Recent ex vivo studies have demonstrated that birefringence mapping enables the characterization of collagen and smooth muscle concentration and distribution in vascular tissues. I...
متن کاملPolarization recovery through scattering media
The control and use of light polarization in optical sciences and engineering are widespread. Despite remarkable developments in polarization-resolved imaging for life sciences, their transposition to strongly scattering media is currently not possible, because of the inherent depolarization effects arising from multiple scattering. We show an unprecedented phenomenon that opens new possibiliti...
