Sebuah Sistem Pencitraan Optik berbasis pada Proyeksi Pola Titik-titik Acak dengan Metode Digital Image Correlation (DIC) untuk Menentukan Profil Kekasaran Permukaan suatu Bahan

Oleh: Karisna, Sasono, Margi, Ardi, Subhan Zul

Reliable methods (techniques) are needed to determine surface roughness accurately. Contact techniques are prevalent but can damage materials and are subject to much noise. Meanwhile, non-contact techniques (usually optical) still face setup complexity and inaccuracy. This paper designs a simple opt...
