In　recent　years,　with　the　rapid　development　of　modern　industry,　the　non-contact　measurement　technology　has　attracted　more　and　more　attention.　As　an　interferometric　measurement　technique,　the　laser　Doppler　vibration　measurement　can　be　applied　to　application　scenarios　where　it　is　difficult　to　obtain　vibration　measurements　through　accelerometers　or　other　surface　contact　sensors.　Since　the　birth　of　the　laser　Doppler　vibrometer　(LDV)　in　1983,　it　has　gradually　become　the　most　widely　used　non-contact　vibration　measuring　equipment　in　various　fields　due　to　its　advantages　of　high　precision,　high　efficiency,　and　portability.　Based　on　the　analysis　of　the　basic　principles　of　LDV,　this　paper　discusses　the　applications　of　LDV　in　agriculture,　life　medicine,　aerospace,　and　construction　engineering　in　recent　years.　©　2022　Universitat　zu　Koln.　All　rights　reserved.
