An interferometry experiment is proposed, working on a Twyman-Green optical configuration. The interferogram is acquired with a digital camera and processed. Using polarization components the interferogram is phaseshifted and four different interferograms are acquired. The experiment is proposed as an introduction to modem phaseshift interferometry, using concepts and laboratory equipment at the level of undergraduate optics courses.

Abstract
An interferometry experiment is proposed, working on a Twyman-Green optical configuration. The interferogram is acquired with a digital camera and processed. Using polarization components the interferogram is phaseshifted and four different interferograms are acquired. The experiment is proposed as an introduction to modem phaseshift interferometry, using concepts and laboratory equipment at the level of undergraduate optics courses.File in questo prodotto:
