What term describes the method used for determining distance when utilizing laser technology in speed measurement?

The method used for determining distance in laser technology for speed measurement is known as "Time of Flight." This concept is based on the principle of measuring the time it takes for a laser beam to travel from the laser device to the target and back. By calculating this time interval and knowing the speed of light, the distance to the object can be accurately assessed.

This measurement is crucial for speed enforcement and is utilized by law enforcement agencies to ensure accurate speed readings. Laser speed measurement devices emit a pulse of laser light toward a moving vehicle. When the laser beam reflects back to the device, the time difference between emission and reception allows the device to calculate the distance accurately, which is essential for determining the speed of the vehicle.

The other terms listed in the question refer to different concepts within speed measurement technology and do not directly relate to the method for determining distance.
