Abstract

Hiperspektralno slikanje je tehnika zajemanja in procesiranja informacij elektromagnetnega spektra. Uporablja se na različnih področjih, kot na primer astronomiji, geologiji, poljedelstvu in prehrambni industriji. Z izboljšavo računalniških tehnologij in digitalnih slikovnih senzorjev postaja hiperspektralno slikanje zanimivo tudi za druge, nove aplikacije. V sklopu skupine za medicinsko fiziko sem sodeloval pri izgradnji hiperspektralnega sistema, ki je predstavljen v zaključni nalogi. Cilj je bil izdelati LED svetilo, primerno za način in področje zajemanja sistema. V nalogi razložim lastnosti LED svetila, svetilnih diod in kontrolnega sistema. Prikažem kako smo svetilo integrirali v aluminijasto ogrodje in v program za zajem slik. Podam dobljene rezultate meritev stabilnosti različnih iteracij svetila in primerjavo s halogenskim svetilom. V zaključku predstavim trenutno stanje sistema in podam ideje za izboljšanje.

Secondary title:	Construction and characterization of LED light source for hyperspectral imaging
Secondary abstract:	Hyperspectral imaging (HIS) is an imaging technique where spatial and spectral information is recorded simultaneously at different spectral ranges of electromagnetic radiation. It is successfully used in many different fields, e.g. astronomy, geology, agriculture, and food industry. With the advancement of computers and digital imaging sensors, HSI is becoming more frequently used in other fields, like medical imaging. As a part of the Medical physics group, I was involved in the design, construction and evaluation of a hyperspectral system prototype which is presented in the thesis. Specifically, the goal of my work was to design, construct and evaluate a LED illumination system. Three different versions of the illumination system including the LED illumination panels, the control system and the integration into the HIS system were constructed. Based on their evaluation and comparison to a halogen illumination, their advantages and drawbacks were identified. At the end, the current state of the system and the ideas for future improvements are described.
