We analyze statistical properties of dynamic speckles formed when an optically rough
surface is illuminated by a fast-deflecting laser beam. The modified space-time correlation …

A principle is proposed for hybrid endoscopes, which combines the advantages of televisual
and multispectral methods of image transmission and supports the diagnosis of cancer and …

A comparative study of two acousto-optic deflectors with different speeds of acoustic wave is
presented in their application to optical distance measurements by using dynamic speckles …

Real-time distance monitoring and thickness measurements of production lines are typical
tasks of the manufacturing process. We demonstrate a novel optical sensor prototype …

The proposed concept of hybrid endoscopes, combining the advantages of television and
multispectral image transmission methods, allows to implement the diagnosis of cancer and …

Noncontact methods of distance measurements to a moving surface using laser light are
relevant for many industrial applications, such as surface profile and position monitoring …

Endoscopes are applied widely for diagnostics of different diseases of internal organs.
However, simultaneous transmission of spectral and spatial information by means of even …

Online control of thickness of as-deposited coatings is of great importance because it directly
affects the quality of protective coatings. We present a novel approach that enables online …

Endoscopes are widely used to diagnose various internal diseases. The most advanced
endoscopes contain miniature television cameras built into the probe which provide high …

In this paper statistical properties of spatially filtered dynamic speckles are considered. This
phenomenon was not sufficiently studied yet while spatial filtering is an important instrument …
