摘要：
The paper considers the distortions of a real holographic image of particles exerting the greatest impact on the image quality: distortions associated with the influence of a virtual particle image and speckle structure of image caused by coherent noises of the medium. The described numerical experiments showed that it is possible to arrange such conditions for hologram recording, its processing and image reconstruction, under which a particle image with the impact of a twin image is suitable for recognizing and determining the characteristics of a particle.
