Modulation of coherence-polarization property of speckles using a birefringent scatterer

Abstract: The change of the spatial coherence-polarization (CP) property of a speckle pattern due to the modulation of birefringence in a scattering medium is investigated experimentally. The birefringence is introduced to the scattering medium by attaching layers of overhead projector (OHP) sheets to it. It is shown that the spatial polarization distribution can be tuned from a uniformly polarized case to a randomly polarized case by increasing the number of OHP sheets. The change of the spatial CP property with the nu… Show more

“…The MRC-based scheme can achieve near-optimal performance while reducing the complexity of the ML-based SM receiver; however, it does not significantly improve the transmission rate [15]. Accordingly, researchers have proposed an optical generalized spatial modulation (OGSM) algorithm [16][17][18][19][20]. However, the definition of GSM in the current literature is not accurate.…”
