Significance: Particle field holography is a versatile technique to determine the size and distribution of moving or stationary particles in air or in a liquid without significant disturbance of the sample volume. Although this technique is applied i

Publikováno v: Journal of Optical Technology. 87:767

The development results of a telescopic system that allows high-quality digital images of distant objects to be obtained in horizontal routes with a high spatial resolution, which in an extreme case tends toward the diffraction limit, are reported in

Optimization-based image reconstruction method for super-resolution structured-illumination microscopy

Autor: F. M. Inochkin, N. R. Belashenkov, V. N. Vasilyev, V. V. Bezzubik

Publikováno v: Journal of Optical Technology. 86:748

This paper discuses the problem of reconstructing images in digital form with resolution that exceeds the limiting resolution of a diffraction-limited system from a set of images with spatially modulated illumination. The reconstruction method descri

Aliasing, coherence, and resolution in a lensless holographic microscope

Autor: Abena S. Amoah, Hai Gong, Michel Verhaegen, Gleb Vdovin, Temitope E. Agbana, V. V. Bezzubik

Publikováno v: Optics Letters, 42(12)
Optics Letters, 42(12), 2271-2274

We have shown that the maximum achievable resolution of an in-line lensless holographic microscope is limited by aliasing and, for collimated illumination, cannot exceed the camera pixel size. This limit can be achieved only when the optimal conditio

Modeling the contrast-sensitivity function of the human visual system

Autor: N. R. Belashenkov, V. V. Bezzubik

Publikováno v: Journal of Optical Technology. 82:711

Based on a representation of the receptive fields of the human retina, a mathematical model has been developed that describes the primary stage of the processing of visual information, taking into account the internal noise of the photoreceptors. The

How phase dispersion of optical coatings affects intracavity second-harmonic generation of laser radiation

Autor: M. V. Inochkin, V. V. Bezzubik

Publikováno v: Journal of Optical Technology. 81:565

This paper discusses how antireflection and reflective optical coatings, as well as the position of a nonlinear crystal inside the cavity, affect intracavity second-harmonic generation. It is shown that phase dispersion of typical antireflection coat

Nonresonant Self-Action of Pulses with a Few Light Oscillation Duration

Autor: V. V. Bezzubik, N. R. Belashenkov, S. V. Sazonov, S. A. Kozlov

Publikováno v: Ultrafast Processes in Spectroscopy ISBN: 9781461377054

The development of laser systems producing the ultrashort laser pulses resulted finally in a creation of laser sources providing the pulses with a duration of several light wave oscillation periods1. Actually the most important question is how do suc

Optimization of algorithms for autofocusing a digital microscope

Autor: S. N. Ustinov, V. V. Bezzubik, N. R. Belashenkov

Publikováno v: Journal of Optical Technology. 76:603

This paper proposes the optimum algorithm for seeking the best focusing position in a microscope with digital image output and makes recommendations for constructing an automatic-focusing system for scanning a sample.
