Kev piav qhia

Cov khoom siv no ua ke nrog Michelson interferometer, Fabry-Perot interferometer, thiab Twyman-Green interferometer hauv ib lub platform. Kev tsim khoom thiab kev tsim ua ke ntawm ntsuas tau zoo heev txo lub sijhawm ntsuas kev kho kom haum thiab txhim kho kev ua tau zoo ntawm kev sim. Tib lub sijhawm, txhua qhov kev teeb tsa yog tsau rau ntawm lub platform me me, uas tuaj yeem tiv thaiv kev cuam tshuam ntawm kev vibration ntawm kev sim. Michelson, Fabry Perot, prism thiab lub ntsej muag cuam tshuam ntawm plaub hom tuaj yeem hloov tau yooj yim, ua haujlwm yooj yim, ua tiav cov txiaj ntsig, cov ntsiab lus sim yog nplua nuj, yog qhov cuab yeej zoo tshaj plaws los ua kom muaj kev cuam tshuam nrog kev sim.
