Active triangulation systems, i.e. using the transmission and reflection of electromagnetic waves other than radio waves

Introduced: January 2006

Full Title

Full titles differ between systems:

IPC:

Systems using the reflection or reradiation of electromagnetic waves other than radio waves, e.g. lidar systems > Systems using the reflection of electromagnetic waves other than radio waves > Systems determining position data of a target > Indirect determination of position data > Active triangulation systems, i.e. using the transmission and reflection of electromagnetic waves other than radio waves

CPC:

Systems using the reflection or reradiation of electromagnetic waves other than radio waves, e.g. lidar systems > Systems using the reflection of electromagnetic waves other than radio waves (G01S17/66 takes precedence) > Systems determining position data of a target > Indirect determination of position data > Active triangulation systems, i.e. using the transmission and reflection of electromagnetic waves other than radio waves

Additional Content IPC

Active system active systems An active system uses a transmitter and a receiver. Passive system passive systems A passive system listens without transmitting.

No child classifications to compare. This is a leaf node in both IPC and CPC.
