Forensic interferometry is a critical tool in crime scene investigation, using laser-based measurements to reconstruct events with high precision. However, outdoor seating—such as benches, chairs, or tables—can introduce unique challenges to this process.

1. Physical Obstruction: Outdoor seating may block or reflect laser beams, distorting interferometry data. This can lead to inaccuracies in distance measurements or spatial reconstructions.

2. Vibrational Interference: Seating structures, especially lightweight or movable ones, can transmit vibrations from wind or human activity, disrupting sensitive interferometry equipment.

3. Thermal Effects: Materials like metal or plastic in seating can expand or contract with temperature changes, altering the crime scene’s geometric integrity over time.

4. Shadowing and Reflections: Complex seating arrangements may cast shadows or create reflective surfaces, interfering with laser alignment and data collection.

To mitigate these issues, forensic teams often document seating positions before analysis, use stabilizing mounts, or employ advanced filtering algorithms to account for environmental noise. Understanding these impacts ensures more reliable forensic outcomes in outdoor settings.
