Abstract
A laser wind tunnel turbulent airflow detection system comprising a laser sensor system and a controller. The laser sensor system is configured to emit laser beams in a wind tunnel from transmitter locations. The laser sensor system is configured to detect the laser beams at receiver locations. The controller is configured to emit the laser beams from the transmitter locations to the receiver locations using the laser sensor system. The controller is configured to determine beat frequencies of the laser beams detected by the laser sensor system at the receiver locations. The controller is configured to determine air turbulence in the wind tunnel for the receiver locations using the beat frequencies.
