title = "Laser differential confocal focal-length measurement and its instrument",
abstract = "Based on our self-proposed laser differential confocal focusing method, we propose a high precision focal-length measurement and develop measurement instruments. Experiments and analyses indicate the measurement uncertainty is prior to 0.01\% from 12000mm to 50000mm.",
