Highly Stable Vibration Measurements by Common-path off-axis Digital Holography

•A novel configuration of a common-path off-axis digital holographic system, with high mechanical stability and compact in size, is proposed.•The decisive advantages of the proposed digital holographic systems are its very simple optical design, compact in size, less-vibration sensitive to external perturbations, and cost-effectiveness as uses fewer optical elements.•The feasibility of the proposed system is demonstrated its capability for vibration measurements of 3D objects using a high-speed camera which is triggered to record the vibration of the object as a function of the time.•Due to its simple geometry and significant outcomes, the proposed system could be established as a powerful tool for a wide range of optical imaging and measurement investigations.
