Abstract

The measurement range of the MicroLiDAR was enhanced with multi-reference paths. The multi-reference paths were composed of four paths with polarization maintaining optical fibers, each with different lengths. 50-mm-long measurement range was demonstrated with an oscilloscope with 15-GHz bandwidth. Reducing the time of calculation of the distance, we induced the dual entry method and demonstrated it. The stable distance measurement was demonstrated up to 50 mm.
