摘　　要：理论上研究分析了相干高斯光束的符合成像和干涉。导出了相干高斯光束的符合成像公式和符合干涉条纹公式,从这些公式可以看出符合成像和干涉是由于两条光路相应的汇聚投射引起的。符合成像和干涉条纹的质量及能见度可以同时很好。我们的结果表明纠缠光子对和相干高斯光束的符合成像及干涉的物理本质是不同的,相干高斯光束的符合成像和干涉的物理本质是光强的点对点投射,而纠缠光子对的符合成像和干涉的物理本质是双光子的振幅关联。We present a theoretical study of coincidence imaging and interference with coherent Gaussian beams. The equations for the coincidence image formation and interference fringes are derived, from which it is clear that the imaging is due to the corresponding focusing in the two paths. The quality and visibility of the images and fringes can be high simultaneously. The nature of the coincidence imaging and interference between with quantum entangled photon pairs and with coherent Gaussian beams are different. The coincidence image with coherent Ganssian beams is due to intensity-intensity correspondence, a classical nature, while that with entangled photon pairs is due to the amplitude correlation, a quantum nature.
