Object characterization with refractometric digital holography
(2004) In Technical Report LUTEDX/(TEAT-7126)/1-6/(2004)- Abstract
- We demonstrate a Digital Holographic method where two different substances
in a blend can be discerned. The method requires only one set of exposures
and one reconstruction in the plane of focus. The large scale phase variation
of the phase image is unwrapped by Flynn’s discontinuity algorithm to reveal
which regions in the sample the phase has decreased or increased upon
transmission of the illuminating wave. Objects with higher or lower index
of refraction than the mounting liquid can be detected as regions where the
phase has been shifted. We also present a method to calculate the volume
distribution of substrates in a sample. Experimental results of both... (More) - We demonstrate a Digital Holographic method where two different substances
