A "Spring oscillator vibration image descriptor" designed specifically for high school and university physics experiments and popular science exhibitions. By using high-definition slow camera, laser trajectory projection, and real-time tracing technology, the displacement time (x-t), velocity time (v-t), and acceleration time (a-t) curves of the spring oscillator are synchronously visualized, helping students and viewers "see" the entire process of harmonic motion. Typical experiment: Classroom demonstration: The teacher starts with one click, and within 3 seconds, a graph is generated. Students visually compare three 90 ° phase difference curves. Group experiment: Students change the mass or stiffness coefficient and observe the changes in the period T=2 π√ (m/k) in real time.
