Seeing is Believing!

Operating Deflection Shape video analysis of equipment operation with amplified motion.

Optical Flow ODS (also known as Motion Amplification ODS™) accurately measures structure surface vibration which is translated into the machine’s overall motion.

Failed structure support pilings of a 15-ton vertical ball mill gear box. Displacement ≈ 10 mills



The recording uses a standard high-speed camera typical of that used in machine vision applications.
