Feedhorn Coating - research report
Václavík, Jan
The report contains a description of the developed methods for metalizing of prototype of the FEEDHORN demonstrator, which is made up of a specially shaped carbon fiber composite carrier and a CNT layer. The report contains the results and comments for future construction of similar types of devices.

Device calibration.
Melich, Radek ; Václavík, Jan ; Žídek, Karel
The device has to be calibrated in absolute terms for its brightness response. This will be facilitated by a combination of an integrating sphere and collimating objective. The emitted total light intensity will be controlled by a reference photodiode inside the integrating sphere.

Measurement of camera spectral response
Melich, Radek ; Václavík, Jan ; Žídek, Karel
Spectral response of the camera will be measured using monochromator in conjunction with an integration sphere. Camera without objective will be placed in one port of the integrating sphere and light beam from monochromator will be fed into perpendicular port. Sensor of the camera sensor will be therefore uniformly illuminated by diffused light from monochromator. Proposed FWHM of the monochromator is 15 nm as a trade-off between light intensity provided by monochromator and deformation of spectral characteristic (Picture XY). Diameter of the integrating sphere has to be larger than 100 mm to ensure uniform illumination over sensor area.

Interpolace obrazů
Václavík, Jan ; Odstrčilík, Jan (oponent) ; Kolář, Radim (vedoucí práce)
Tato bakalářská práce se zabývá porovnáváním některých interpolačních metod, při použití na různé druhy šedotónových 2D obrazů. Z hlavní části je zaměřena na lineární, kvadratickou a kubickou metodu a jejich kvalitativní vyhodnocení pro několika násobnou změnu obrazového rozlišení. K samotnému provedení analýzy je použito programové prostředí Matlab.
