Optical Set-up for Small Volume of Liquid Surface Tension Measurement
Hošek, Jan ; Studenovský, K.
The goal of the presented work is to optimize the experimental set-up of the end-tip meniscus planarity observation and detection in the case of Furgeson method for small volume of liquid surface tension measurement. A new, compact and sensitive experimental optical set-up is designed for the meniscus planarity measurement.
Jednoobjektivový systém pro měření pozice a velikosti bublin
Hošek, Jan
Modern symmetry group theory provides constructive procedures for finding similarity transformations and invariants, leading to fundamental change in the similarity solutions of shear flows, based so far on inspection analysis, ad hoc assumptions, and physical considerations. The new approach is here demonstrated on classical Stokes' (1851) problem of the suddenly accelerated flow above a stationary flat plate, with the gradual growth of boundary layer thickness.
Color correction of Olympus C-750 UZ camera with removed IR filter
Hošek, Jan
The goal of the work is to search an appropriate comerctial available filter for color correction of Olympus C-750 UZ camera with remover IR filter. Next we developed numerical algorithm for camera color correction in case of presence of no mechanical filters.
Numerical Simulation Adjustment Errors of Hyperbolic Optical Surfaces Quality Testing
Hošek, Jan
An numerical simulation of adjustment errors of Hindle interferometric hyperbolic optical surface testing set-up was performed. A Numerical simulation program was written in Matlab for determination of numeric evaluation of set-up adjustment errors as a function of wavefront deformation.

Apparatus Design for Small Volume of Liquid Surface Tension Measurement
Hošek, Jan ; Studenovský, K.
The work deals with evaliaton of condition for measurement of surface tension of liquid in capilary by Furgeson mehtod. On the bases of theoretical discussion was developed a new method of measurement of surface flatness of very small dimension.
Alignment Error in Optical Hyperbolic Surfaces Testing
Hošek, Jan
A numerical program for alignment error evaluating of hyperbolic optical surfaces testing system. A numerical evaluation of acceptable errors for testing was done. A numerical simulation of interference fringes shape of each king of error was presented.

Spatial vapour density measurements inside laser induced cavitation bubbles
Hošek, Jan ; Garen, W. ; Shönig, H.
Cavitation bubbles have been studied and reported as an undesirable side effect in many of the medical application used of laser ablation like eye or cardio surgery in recent years. Our intention was to gain a physical information about processes inside the cavitation bubble. We develop a new technique for direct gas/vapour property measurements during the cavitation process in the bubble based on determination of bubble gas density.
