Abstract
A millimeter wave energy sensing wand includes a housing adapted to be grasped by a hand of an operator. A number of sensors may be coupled with the housing and include comprising at least one millimeter or terahertz wave energy sensor. A controller coupled with the housing and electrically coupled with the sensors receives signals from the sensors in two or more sensing modes, including an active sending mode and a passive sensing mode, and generates feedback when an anomaly is detected in the received signals. The sensors may also operate in a metal detection sensing mode, and the controller may further generate feedback based on the metal detection sensing mode. The sensors may further be configured to operate in a proximity sensing mode. One or more LEDs may illuminate a portion of a scanning area.
