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.
Pulsní speklová interferometrie
Dvořáková, Pavla ; Bajgar, Vlastimil ; Trnka, Jan
The contribution deals with an application of ESPI for measuring a deformation profile of a thin steel plate loaded by a focusing a ruby laser beam. Monitoring of the normally loaded test-object determined Michelson-type ESPI sensitive to out-of-plane displacement.
