Core Research Progress

Traditional stereoscopic imaging cannot simultaneously deliver large measurement range, high precision and high-speed acquisition. This work proposes an innovative time-domain stereoscopy mechanism. By integrating femtosecond electro-optic combs and nonlinear sampling techniques, it achieves high-precision ranging based on time-domain disparity signals. The system attains a meter-scale measurement range with hundred-nanometer precision, and performs millisecond-level dynamic measurement on 47 million points, overcoming the performance bottlenecks of conventional 3D imaging.

Technical Application Value

This technology pioneers the time-domain stereoscopy solution, resolving the trade-off between range and precision in 3D imaging. It boasts high density, high precision and high-speed measurement performance. Suitable for surface metrology, mechanical dynamic monitoring and quality control in precision manufacturing, it provides a new technical foundation for high-end precision 3D perception and measurement.
