Reaching micro-arcsecond astrometry with long baseline optical interferometry; application to the GRAVITY instrument
S. Lacour, F. Eisenhauer, S. Gillessen +10
A basic principle of long baseline interferometry is that an optical path difference (OPD) directly translates into an astrometric measurement. In the simplest case, the OPD is equ…
