20.500.12556/DKUM-72376 Spektralno razločevanje Fabry Perot interferometra z nizkoločljivim spektralnim analizatorjem Spectral distinction of Fabry-Pérot interferometer with low-level spectrum analyzer V diplomski projektni nalogi smo izdelali senzor, s katerim lahko zaznavamo spremembo dolžine Fabry Pérot interferometra. To spremembo lahko izračunamo preko spremembe faznega kota spektralne karakteristike našega senzorja. Fazni kot lahko uporabimo za nadaljnje izračune pozicije ali majhnih premikov, izračun sile, ki deluje na senzor, spremembo temperature v okolici interferometra in druge dejavnike, katerim je izpostavljen Fabry Pérot interferometer. Najprej je predstavljeno teoretično ozadje interference in Fabry Pérot interferometra, nato merilna proga, ki je uporabljena na našem senzorju. Sledi kratka predstavitev prototipa, narejenega na mikrokrmilniku Arduino mega in programskem orodju Processing 3. Opisana je izgradnja in načrtovanje ohišja za spektralni analizator, vezje, ki je potrebno za delovanje LED luči, tako da lahko z njo upravljamo preko mikrokrmilnika. Nekaj besed o spektralnem analizatorju, mikrokrmilniku in pa izdelavi tiskanega vezja. Na koncu pa še rezultati in meritve, ki smo jih pridobili s senzorja. In project for diploma we have created a sensor that detects a change in lenght of fabry perot interferometer. The change of lenght can be calculatet if we know the change in phase angle from spectral characteristic of sensor and later we can calculate a position or smal displacement that efects the sensor, we can alos calculate force acting on the sensor, even a change in temperature surrounding the interferometer and variouse other factors to which Fabry Perot interferometer is exposed. First is represented the theoretical background of interference and Fabry Perot interferometer, then measurment track of the sensor followed by brief introduction of prototype made on Arduino mega microcontroller and software Processing 3. There is also included explanation of casing design for the spectrum analyzer and circuit which is needed for operating LED light via microcontroller. At the end there are some words about the spectrum analyzer, microcontroller and printed circuit board followed by results of the measurements we obtained from the sensor.
