Abstract:V diplomski nalogi je opisana izdelava merilnika lomnega količnika tekočin, ki temelji na osnovi fresnelovega odboja na koncu optičnega vlakna. Lomni količnik je določen glede na odbojno svetlobno moč med dvema medijema, ki je zajeta na fotodetektorju in v kombinaciji s transimpedančno stopnjo tudi ojačana. Merilnik je zmožen meritev izvajati neprekinjeno hkrati pa je točen in cenovno ugoden.
Keywords:lomni količnik, Fresnelov odboj, transimpedančna stopnja, svetleča dioda, fotodetektor.

Title:Measurement of the refractive index of fluids based on Fresnel reflection at the tip of an optical fiber
Abstract:Study describes the production of a refractive index fluid gauge based on a fresnel reflection at the tip of an optical fiber. The refractive index is determined by the light reflected between the two media, which is captured on the photodetector and, in combination with the transimpedance amplifier, is also amplified. The gauge can measure continuously while being accurate and affordable.
Keywords:refractive index, Fresnel reflectance, transimpedance amplifier, LED, photodetector.
