Laser / Lidar Speeding Ticket Expert - By Perry Zucker

Lidar / Laser Speeding - How  Police Laser / Lidar  Works? (Theory):

Laser / Lidar speed measuring devices that are used to issue laser / lidar speeding tickets, utilize a method of an invisible (infrared) light beam that has various beam widths, which depends on the specific laser unit and distance.


The police officer activates the unit at a moving target (vehicle). The unit emits a series of light beams with a known frequency, in the infrared range of the spectrum, averaging the errors of distances.

to use on the trial date.This might include maintenance, calibrations, training, and other data records. Police Officers that issue lidar / laser speeding tickets / violations are "Experts" in the operation and not the theory of the aforementioned devices. Logically the best defense, is to retain an "Expert / Expert Witness" in this exact field.  The expert should be an engineer, that is familiar with laser / lidar (gun) speed measuring device (certified speed measuring device operator / instructor), police training , vehicle characteristics, certified vehicle technician/ mechanic, as well as court rules.  Usually trial by declaration (mail) rarely is successful (selected states).

The beam strikes the target and is reflected back to the unit with a designated time / frequency. The unit calculates the time difference, which is known as d t and the difference in distance d d. The laser / lidar unit's final calculation is velocity (v = d d/d t; d: distance). The Greek symbol "d d " is defined as the difference (X2 - X1).


The officer observed the target vehicle (yours / defendant) and reads the speed display of the laser/ lidar unit - By Perry Zucker


Police Lidar / Laser - Standard Operating Procedure:

The officer performs a series of tests (as per manufacturer / state / federal), which may assist the operator in determining if the Laser / Lidar unit is operating.
