Scanning, Laser Rangefinder.

Our rangefinder is a commercially available scanning laser rangefinder from Acuity Research [21]. It is a time-of-flight rangefinder that can acquire range data at up to 50K samples/sec. It can accurately determine range from 0 to 15 meters, with better accuracy at closer ranges.

The scanning mirror sweeps the laser beam in a vertical plane with a 60$^\circ$ occlusion (aimed downward). The scanning mirror has a 4096-position shaft encoder to aid in determining where the laser is aimed.
