The present invention discloses a suspended rear-projection volumetric display system and method with a constant optical path. A vibration table, a reflection table, and a rear-projection table are arranged vertically in sequence from bottom to top. The vibration table is fixed, the reflection table is elastically connected to the vibration table via a first elastic member, the second reflector is fixed to the reflection table, the rear-projection table is elastically connected to the reflection table via a second elastic member, and the imaging screen is fixed to the rear-projection table, with the imaging plane being horizontal. Projection light emitted by a projector is reflected by the first and second reflectors in sequence, and then passes through the rear-projection table to illuminate the imaging screen from the back, forming an image on the front of the imaging screen. The rear-projection volumetric display is performed using the imaging screen's vibration range as the imaging area. The present invention can produce clear and uniform images regardless of the amplitude of the rear-projection table's vibration or the real-time height of the moving imaging screen, thereby obtaining clear voxels of uniform size. When the mass of the reflection table is significantly smaller than that of the rear-projection table, the force amplitude acting on the frame can be significantly reduced, thereby significantly reducing the counterweight mass of the entire device.
