Schwartz Electro-Optics has adapted its laser range-finder and imaging technology to control  agricultural spraying . The precision possible with the Treesense system cuts overspraying. Result: minimal environmental impact and cost savings on sprayants.

Treesense is based on Schwartz’s Autosense II vehicle detection and classification system that scans an eye-safe infrared indium gallium arsenide pulsed diode laser beam. A silicon avalanche photodiode detector senses the reflected beam.

In  agricultural  applications, the sensor detects the presence and extent of foliage on each side of the sprayer.  Spraying  is limited to those volumes
