提出了一种利用数字全息术测量不透明微纤维尺寸、取向和位置的方法。该方法包括记录数字全息图，然后在不同深度进行重建。自动图像分析和统计技术的新型组合应用于重建数字全息图的强度，用于准确确定微纤维的特征。所提出的方法的性能进行了验证与已知的长度和方向的单纤维。通过将其应用于纤维在液体介质中的悬浮液，进一步证明了该方法用于测量纤维长度的潜力。
A method to measure the size, orientation, and location of opaque micro-fibers using digital holography is presented. The method involves the recording of a digital hologram followed by reconstruction at different depths. A novel combination of automated image analysis and statistical techniques, applied on the intensity of reconstructed digital holograms is used to accurately determine the characteristics of the micro-fibers. The performance of the proposed method is verified with a single fiber of known length and orientation. The potential of the method for measurement of fiber length is further demonstrated through its application to a suspension of fibers in a liquid medium.
