We present single-exposure SNR-enhanced holography (SE-SEH). In SE-SEH, three beams with different wavelengths simultaneously illuminate the sample (particle field) with varied oblique directions, a color CCD records the light transmitted through the sample. The information included in each color channel is retrieved by analyzing the RGB channels, and processed with a chromatic aberration corrected SEH reconstruction method. Experimental results show that SE-SEH can mitigate fixed pattern noise originating from multiple interferences between different optical interfaces, the artifacts resulting from diffraction by adjacent particles, the twin-image and the artifacts due to out-of-focus particles using a single illumination shot, making it attractive for the study of particles with fast events and dynamics.

我们提出了单曝光SNR增强全息术（SE-SEH）。在SE-SEH中，具有不同波长的三束光束同时以不同的倾斜方向照亮样品（粒子场），彩色CCD记录透过样品的光。通过分析RGB通道来检索每个颜色通道中包含的信息，并使用色差校正SEH重建方法进行处理。实验结果表明，SE-SEH可以减轻由不同光学界面之间的多重干扰，相邻粒子衍射产生的伪影，双像以及单聚焦拍摄导致的散焦粒子引起的伪影引起的固定模式噪声。使其对具有快速事件和动力学的粒子的研究具有吸引力。
