Aplikace anamorfotické optiky pro měřicí účely
Hošek, Jan
This paper presents an application of anamorphic optical system onto determination radius and position in 3D-observation space spherical objects using the single camera. Three kinds of optomechanical design of the anamorphic optical system are presented and appropriate basic theoretical principle of the instrument is described.

Jednoobjektivový zobrazovací a měřicí systém
Hošek, Jan
This paper presents a new optical system, which allows to determinate radius and position of a number of spherical shape objects in 3D-observation space using the only one monolens camera system. The principle of the system is based on anamorphotic optical system and appropriate data processing algorithm. The goal of the presented work was to develop the first experimental and measurement set-up of this method, which confirm the theoretical expectation and allows to perform the first experimental measurement and experiences.

Použití klasického digitálního fotoaparátu pro fotografii v blízkém IR záření
Hošek, Jan
The goal of the presented work was to use the standard CCD photographic camera for visualization of near IR spectral source. Almost every standard CCD camera chip is usually sensitive not only in visible spectral range but the maximum of spectral sensitometric characteristics of CCD chip is around wavelength 800 nm. In order to be possible take snapshots with standard CCD photographic camera without color distortion caused by near IR illumination the sensitivity of the camera chip is artificially decreased.

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.
