Abstract

Telah dilakukan penelitian pengukuran getaran suatu obyek dengan menggunakan interferometer Michelson dan CCD webcam. Pola intereferensi dihasilkan dari perbedaan lintasan laser HeliumNeon dengan panjang gelombang 632,8 nm melewati obyek getar speaker piezo yang diletakkan pada cermin uji. Pemberian frekuensi getar dimulai 5 Hz – 30 Hz dengan kelipatan 5 Hz serta frekuensi 1 KHz-20 KHz dengan kelipatan 1 KHz. CCD webcam dapat merekam berkas sinar laser dari cermin referensi dan cermin uji dengan kemampuan CCD webcam 30 frame perdetik. Perubahan intensitas laser yang menggambarkan frekuensi getar obyek dapat dilihat pada frekuensi di bawah frekuensi CCD webcam.
