光学扫描全息术是一种功能强大的全息记录技术，只需一次二维扫描即可记录三维信息。与标准的数字全息术一样，为了重建截面图像，必须对生成的数据进行后处理以获得截面内容。我们提出了一种盲截面图像重建技术，以实现数据处理的自动化。这种重建利用边缘信息自动确定合适的菲涅耳波带板，并应用逆成像来恢复断层图像，显著抑制了散焦噪声。用于验证算法的实验数据是从光学扫描全息系统的物理实现中测量出来的。
Optical scanning holography is a powerful holographic recording technique in which only a single two-dimensional scan is needed to record three-dimensional information. As in standard digital holography, for the reconstruction of a sectional image, the resulting data must then be postprocessed to obtain sectional content. We propose a blind sectional image reconstruction technique to automate the data processing. This reconstruction uses edge information to determine the appropriate Fresnel zone plates automatically and applies inverse imaging to recover the sectional images with significant suppression of the defocus noise. The experimental data used to verify the algorithm are measured from a physical implementation of the optical scanning holography system.
