20.500.12556/RUL-148470 Laserski žiroskop Laser Gyroscope Laserski žiroskopi so nepogrešljivo orodje v sodobni navigacijski tehnologiji in so uporabljeni v različnih aplikacijah, od letalstva do pametnih telefonov. Temeljijo na Sagnacovem pojavu, ki omogoča določanje sprememb kotne hitrosti s pomočjo optične interference. V sklopu zaključne naloge sta bila sestavljena laserski žiroskop ter mehanizem za vrtenje s konstantno kotno hitrostjo. Med vrtenjem smo s fotodiodo opazovali frekvenco utripanja na osciloskopu ter iz signalov popisali občutljivost žiroskopa ter ugotovili zaklepno kotno hitrost. S tem smo podrobneje spoznali delovanje instrumenta ter pripravili laboratorijsko vajo za prihodnje generacije študentov. Laser gyroscopes are an indispensable tool in modern navigation technology and are used in various applications, from aviation to smartphones. They are based on the Sagnac effect, which allows for determining changes in angular velocity using optical interference. As part of the final thesis, a laser gyroscope and a mechanism for rotating at a constant angular velocity were assembled. During the rotation, we observed the beat frequency on the oscilloscope with a photodiode and from the signals, we recorded the sensitivity of the gyroscope and determined the lock-in angular velocity. With this, we gained a more detailed understanding of the operation of the instrument and prepared a laboratory exercise for future generations of students. laserski žiroskopi Sagnacov pojav laserji He-Ne krožni resonatorji zaklepni pojav frekvenca utripanja laser gyroscopes Sagnac effect He-Ne lasers ring resonators lock-in effect beat frequency true false false [G.
