Abstract

Instrument for undersøkelse av et objekt (12) omfattende et bevegbart interferometer med en laserkilde og flere detektorer (24) innrettet i en rekke. Laserkilden ekspanderes og er innrettet til å rette en konvergerende objektstråle (21) mot et punkt (22) eller linje utenfor objektet (12) hvorved et flekket mønster av lys reflektert fra objektet (12) detekteres av detektoren eller detektorrekken (24). Punktet (12) eller linjen mot hvilket laserkilden er innrettet til å konvergere objektstrålen (21) befinner seg omtrent i samme avstand fra objektet (12) som objektet befinner seg fra kilden. Bevegelseshastigheten til instrumentet, samplingsraten til detektorene (24) og størrelsen på området (23) av objektet belyst av den konvergerende laserobjektstråle (21) er innrettet slik at de sekvensielle deler (23) av undersøkelsesobjektet (12) overlapper hverandre.
