Camera Relay System Using a Motor Equipped with a Mechanical Brake to Capture Micro-Vibrations of Moving Objects.

We constructed a camera relay system using a motor equipped with a mechanical brake to reduce the constant micromovement caused by the noise control system of a mirror-driven active vision system that enables high-speed magnified tracking imaging and measures the micro-vibrations of a moving object. We verified that the proposed motor equipped with a mechanical brake achieved a noise reduction that was approximately five times higher than that achieved by a conventional motor without a mechanical brake. As a result, we measured 0.01 pixels, a 0.08 mm magnitude of micro-vibrations in a wide range of lateral direction with respect to $\boldsymbol{0.16}\ \mathbf{m}\times \boldsymbol{0.09}\ \mathbf{m}$ of the camera-field angle.
