Abstract
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 microfibers.
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.
