中文摘要：
我们调查使用货车 Cittert-Zernike 定理从高力量的多薄片红 LEDs 产生的光的空间连贯。从多薄片 LEDs 产生的光在繁殖以后演变为部分协调的光，这理论上被表明，并且空间连贯随繁殖距离的增加被增加。而且，光的空间连贯被发现是仔细与多薄片 LEDs 的薄片分发有关。光的空间连贯的分发被幼仔双裂缝干扰试验性地检验。试验性的结果与理论的一致，这被发现。
英文摘要：
We investigate the spatial coherence of the light generated from high-power multi-chip red LEDs by usmg the van Cittert- Zernike theorem. It is theoretically demonstrated that the light generated from multi-chip LEDs evolves into partially coherent light after propagation, and the spatial coherence is increased with the increase of propagation distance. Moreover, the spatial coherence of the light is found to be closely related to the chip distribution of multi-chip LEDs. The distribution of the spatial coherence of the light is experimentally examined by Young＇s double-slit interference. It is found that the experimental results are consistent with the theoretical ones.
