optical lever detection

Optical lever detection uses a laser beam and a mirror to measure tiny movements or displacements of an object with high precision. When the object moves, it tilts or shifts the mirror, causing the reflected laser beam to change its position on a distant detector. By analyzing these shifts, we can determine the small movements of the object very accurately. This method is often used in sensitive measurements like seismic sensors or atomic force microscopes, leveraging the laser’s precision and the mirror's responsiveness to detect extremely slight changes in position.
