Laser transponder to power a laser based speed monitor

摘要

A laser transponder for disabling a laser-based speed monitor which is transmitting a monitor laser beam at a moving vehicle by transmitting a jamming laser beam to the laser-based speed monitor. The monitor laser beam is in the shape of a monitor signal that includes monitor pulse trains emitted at a first frequency, while the jamming laser beam is in the shape of a jamming signal that includes jamming pulse trains emitted at a second frequency.
