The preservation of cultural heritage requires non-destructive techniques to assess the condition of historical artifacts. This study examines the dynamic behavior of a timber altarpiece replica, covered with traditional plaster and painted layers, using laser vibrometer technology. The goal is to analyze its response to low-volume sound levels and to detect early signs of delamination by identifying increased vibration amplitudes in compromised areas. This approach effectively detects vibration patterns that indicate potential delamination before visible damage occurs, highlighting the value of laser-based techniques for non-destructive diagnostics and the preservation of cultural heritage.
