We consider a holographic study of particles. The main attention is focused on retrieval of information from a digital hologram, namely, determination of the characteristics of a particle and its holographic image. To estimate the efficiency of this stage, we used quantitative criteria of the holographic image quality. These criteria were also used for determining the position of a particle in space, which ensures a significantly higher accuracy (an error of about 0.2 mm) compared with other methods. An algorithm for increasing the quality of the holographic image of a particle is developed. A method for two-dimensional holographic mapping of the volume of the medium with particles for automatic retrieval of information from the digital particle hologram is discussed.
