Summary

Automatic Translation

Her presenterer vi en protokoll for å bygge en rask Brillouin spektrometer. Cascading nesten avbildes fase array (Vipa) etalons oppnå en måling hastighet mer enn 1000 ganger raskere enn tradisjonelle skanning Fabry-Perot spektrometre. Denne forbedringen som sørger for Brillouin analyse av vev og biomaterialer ved lave effektnivåer in vivo.
