Abstract

U ovom radu dana je teorijska podloga rada interferometra. Opisana je povijest mjeriteljstva i njezina važnost u razvoju ljudske civilizacije. Sustav akvizicije signala opisan je na način na koji radi, prihvaća i obrađuje podatke da bi dobili mjerljive rezultate. Razvijen je optoelektronički sustav s fotodiodom za detektiranje promjene napona kod izmjene konstruktivne i destruktivne interferencije svjetlosti. Nakon razvijanja sustava, od gotovih optomehaničkih elemenata izrađen je interferometar te postavljen na postojeći jednoosni mjerni uređaj u Nacionalnom laboratoriju za duljinu. Izračunato je dozvoljeno odstupanje od pravocrtnosti pomičnog kraka interferometra u odnosu na aktivnu površinu diode.

Nakon instaliranja interferometra provedena su i preliminarna mjerenja. Rezultati su prikazani u grafičkom i tabličnom obliku.

Abstract (english)

In this scientific work (article) is given theoretical background of interferometer. It is described history of measurement and its importance in evolution of human civilization. Data Acquisition System is described how it works, accepts and process information so we can get measurable results. It is developed optoelectronic system with photodiode to detect voltage change with changes of constructive and destructive interference of light. After system being developed, from finished modules interferometer was made and set on existing 1D measurement device in the National Laboratory for Length. It is calculated tolerance of straightness of moving arm compared to active surface of photodiode.

After interferometer being installed measurements were carried out. Results are shown in graphic and tabular form.
