研究目的
To present a non-scanning, single-shot, 3D integral microscopy method with optical sectioning based on the combination of Fourier-mode integral microscopy with a 3D deconvolution technique.
研究成果
The presented method enables non-scanning, single-shot 3D integral microscopy with optical sectioning, offering potential applications in video-rate 3D reconstruction of microscopic samples. The technique effectively removes out-of-focus light, enhancing the contrast and resolution of the reconstructed images.
研究不足
The method's effectiveness depends on the accurate calculation of the synthetic 3D impulse response function and the selection of an optimal Wiener parameter for deconvolution.
1：Experimental Design and Method Selection:
The method combines Fourier-mode integral microscopy with a 3D deconvolution technique. A synthetic 3D impulse response function is used for deconvolution.
