This is the second volume of a two-volume guide to designing, conducting and interpreting
laboratory and field experiments in a broad range of topics associated with hydraulic …

We propose a novel system allowing remote control of the location of the extended focal
depth region. This system may find applications in situations where controllable optical …

We study the interference of two intersecting similar Bessel beams. The front waves of the
two beams interfere to form a distinct pattern of parallel fringes superimposed on the circular …

The details of a technique to measure solid surface velocity and detect particle movement
are presented. This technique is based on the measurements of the frequency change of …

The on-axis intensity distribution of a beam generated by a Fresnel axicon (fraxicon) is
experimentally and numerically examined and compared to a classical axicon …

The scattering effect of a circular aperture, located in an impedance plane, on a Bessel
beam is investigated by decomposing the scattered wave into two subcomponents, namely …

In this thesis we explore the use of Laser Bessel beams in solid surface and fluid velocity
measurements. We present a novel simple technique to measure two velocity components …

The laser Doppler field sensor presented in this paper is suited for high resolution flow
velocity field imaging on the micro scale without use of a camera. The field sensor is …

The article considers the possibility of constructing laser Doppler velocity vector meters
based on a bichromatic source of spatially combined Gaussian or Bessel beams, the two …
