用热光观测强度-强度相关散斑图

Observation of Intensity-Intensity Correlation Speckle Patterns with Thermal Light

Li-Gang Wang, M. Al-Amri, M. Suhail Zubairy

摘要:

在传统的Hanbury Brown和Twiss(HBT)格式中,热强度-强度关联是相位不敏感的。在这里,我们提出了一个修改的HBT计划与相位共轭证明的相位敏感和不可因式分解的功能,热强度强度相关散斑。我们的计划导致的结果是类似的双光子散斑。我们讨论了实验实现的可能性。这些结果为我们提供了一个更深入的了解的热相关性,并可能导致更显着的应用在成像和散斑技术。

英文摘要:

In traditional Hanbury Brown and Twiss (HBT) schemes, the thermal intensity-intensity correlations are phase insensitive. Here we propose a modified HBT scheme with phase conjugation to demonstrate the phase-sensitive and nonfactorizable features for thermal intensity-intensity correlation speckle. Our scheme leads to results that are similar to those of the two-photon speckle. We discuss the possibility of the experimental realization. The results provide us a deeper insight of the thermal correlations and may lead to more significant applications in imaging and speckle technologies.
