SYSTEM FOR IN VIVO ANALYSIS OF TEAR FILM IN THE HUMAN EYE VIA PHASE SHIFTING INTERFEROMETRY

摘要

An in vivo method of characterizing dynamic tear films has been developed using a near infrared phase-shifting interferometer. This interferometer continuously measures light reflected from the tear film, allowing precision analysis of the dynamic surface topography. Movies showing the tear film behavior may be generated along with quantitative metrics describing the tear film surface as it changes in time.
