Correlation imaging is attracting more and more attention as a novel imaging technique taking advantage of the high-order coherence of light fields. To reconstruct an image of the object, many frames of different speckle patterns are required. Therefore, the speed of imaging is strongly limited by the speed of the refreshing rate of the light field. We propose a coprime-frequencied sinusoidal modulation method for speckle pattern creation using a spatial light modulator in a computational ghost imaging system to increase the speed of imaging. The performance of the proposed method is discussed as well.

提出了基于空间光调制器(SLM)进行相位调制产生赝热光源的方案，并讨论了不同空间光调制器的像素阵列的排布方式对关联成像的影响，着重对空间光调制器的像素阵列排布方式进行了基于遗传算法的优化设计方法的研究，以提高赝热光场性能。结果表明，空间光调制器方案克服了毛玻璃方案的局限性，其产生的赝热光二阶关联性好，满足关联成像的需要，系统成像质量较高，该方案对新型关联成像赝热光源设计具有重要参考意义。
