Abstract

An agricultural system with an agricultural harvester has a terahertz sensor. The terahertz sensor includes at least one a terahertz source disposed to direct electromagnetic radiation toward a harvest material of the agricultural harvester. A terahertz detector is disposed to detect the terahertz electromagnetic radiation after the terahertz electromagnetic radiation interacts with the harvest material. A controller is operably coupled to the terahertz detector and is configured to detect a harvest-related parameter based on a signal from the terahertz detector and to perform an action based on a detected parameter.
