    In this study, we present a method for measuring small amplitude vibrations using a high-speed camera. We project a laser onto an object to generate a speckle pattern that is then magnified using a lens and analyzed using a steerable pyramid. This vibration measurement method allows us to separate and measure vibrations based on the direction of the image. We demonstrated the effectiveness of our method by comparing it with traditional methods that do not generate a speckle pattern. Furthermore, we confirmed the validity of our methodology through frequency comparison experiments with a piezo accelerometer that is commonly used for vibration measurements. This novel approach to vibration measurement methodology can significantly advance research in this field.
