Key Points

The auxiliary interferometer achieves dynamic range correction for LiDAR systems, enhancing measurement accuracy.
With a 0.3-meter optical-path difference, the correction method is highly efficient at 20-meter ranging.
Velocity is improved at 200 mm/s while addressing the limitations of swept-source linewidth.
This approach utilizes optical-clock Hilbert-transform resampling to improve timing precision.

Implication

Demonstration of a silicon-based LiDAR correcting timing jitter with a silica-based auxiliary interferometer.

Abstract

Through low-dispersion silica-based auxiliary interferometry with 0.3-meter optical-path difference, 66-times shorter than the measured distance, a silicon-based LiDAR is demonstrated for the 20-meter ranging, limited to swept-source linewidth, and 200-mm/s velocity, through optical-clock Hilbert-transform resampling.
