Microparticle characterization using digital holography

Digital holography is an effective 3D imaging technique, with the potential to be used for particle size measurements. A digital hologram can provide reconstructions of volume samples focused at different depths, overcoming the focusing problems encountered by other imaging based techniques. Several particle analysis methods discussed in the literature consider spherical particles only. With the object sphericity assumption in place, analysis of the holographic data can be significantly simplified. However, there are applications, such as particle analysis and crystallization monitoring, where non-spherical particles are often encountered. This paper discusses the processing of digital holograms for particle size and shape measurement for both spherical and arbitrarily shaped particles. An automated algorithm for identification of particles from recorded hologram and subsequent size and shape measurement is described. Experimental results using holograms of spherical and non-spherical particles demonstrate the performance of the proposed measuring algorithm.     

Accurate size measurement of needle-shaped particles using digital holography

In this paper, a digital holography based method is proposed to accurately measure the length and orientation of the needle-shaped particles in solution. The method involves recording of the hologram and numerical reconstructions (focusing) of the hologram at several depths. An image analysis routine is then used to determine the length, location and orientation of the particles from the reconstructed images without any a priori information about the orientation of particles. The performance of the method is verified using a single fiber with known size and orientation. Subsequently, the proposed method is applied to a suspension of fibers, where the length measurements are found to be in good agreement with the true values. This proposed technique can overcome the shortcoming of existing 2D imaging tools, which can provide only the projected lengths of randomly oriented particles.     

Unifornity of hologram recdrding and weak beam amplification in LiNbO3 fur illumination by beams wth orthogonal mid parallel polarization

Some results of photorefractive investigations in LiNbO₃ are not explained within well-accepted models [1]. New qualitative explanations are proposed, showing that the hologram recording by beams both with orthogonal and with parallel polarizations is caused by the photovoltaic current flowing along a polar axis. In this paper the model is proposed which explains physical foundation of nonshift hologram amplification. He have demonstrated that the big nonstationary amplification is caused by a recording in transition period.

Polymer holography II – The theory of hologram growth

The theory describing in molecular terms radical photopolymerization due to which the refractive index modulation distribution producing a hologram is formed. The theory extends the usual only-diffusion concept to early stages of polymerization, where the opposite diffusion of short polymers (oligomers) is possible which is reduced with increasing polymerization degree. The results of the theory are compared with our experimental results. The idea that, inversely, the experimentally detected curves describing the hologram growth may be used for the study of polymerization kinetics is put forward.
