Interferometric research methods in a ballistic experiment

Abstract

Interferrometric methods are applied in many different fields of research particularly during the phase of rapid dynamic processes. Among them, there is a special place for techniques by coherent sources of light which, along with the perfection of classic types of interferometers, create new possibilities for research work. The development of lasers the order of fs pulse length as well as the recording technique approaches the borderline connected to the fundamental resolutions of measuring process. In this paper, some of the optical methods are analyzed, with the accent on those of interferrometric type, the layout of the experiment, the results on specific geometric shapes and some aspects of noise and scattering.

Interferometrijske metode ulaze u mnoge oblasti istraživanja, pogotovo u fazi brzih dinamičkih procesa. Posebno mesto imaju tehnike sa koherentnim izvorima svetlosti, koje, pored usavršavanja klasičnih tipova interferometara, otvaraju i nove mogućnosti istraživanja. Razvoj lasera dužine impulsa reda fs, kao i tehnika zapisa približavaju se granicama vezanim za fundamentalne rezolucije procesa merenja. U radu su razmatrane neke od optičkih metoda, sa akcentom na one interferometarskog tipa, skicom eksperimenta, rezultatima na specifičnim geometrijskim oblicima i nekim aspektima šuma i rasejanja.
