Laser Speed Detector Calibration

Jurisdictions vary regarding how frequently speed measuring devices must be calibrated.

Laser speed detector calibration. Unlike police radar guns which send a big blast of radar waves down the road that anyone running a radar detector can easily pick up on ahead of time police laser or lidar guns send a pinpoint beam of light that s specifically aimed at just one vehicle at a time. Incorrect calibration or lack of maintenance. We have a dedicated facility capable of calibrating both k and ka band radar speed detection equipment including fixed location detectors mobile vehicle mounted detectors and the speed. Speed measuring devices generally require regular calibration and maintenance to provide accurate measurements.

However the reliability of radar devices depends on whether police kept them in good working order. In a 6 1 decision the supreme court ruled that while the scientific principles underlying the technology of radar or laser. So if you re planning to fight a speeding ticket that was based on radar you ll typically want to obtain the radar calibration records. Our calibration systems however are not vendor specific and use first principles of doppler shift for radar and time of flight for laser based devices.

Our lasers can take a measurement within 0 3 seconds so by the time your detector recognizes our laser s signal the officer will already have a speed reading on you. This has the advantage of making it easier for the officer to tell which vehicle he is getting a. Unlike police radar which directly determines a vehicle s speed by measuring its doppler speed induced frequency shift police lidar calculates speed by observing the changing amount of time is takes to see a series of reflected pulses of. Split second measurements are the norm for our lasers rendering radar and lidar detectors useless.

If the device wasn t. Police laser is very accurate and can often determine you speed to the 10th of miles per hour. Generally a certified technician must calibrate the device every 60 days to three years. Manufacturers of the devices recommend calibration before every use but states may require testing and calibration much less frequently.

The results of radar or laser speed measuring devices can be admitted in court to convict speeders without an expert witness testifying to or noting any prior ohio court ruling affirming the scientific principles of the technology the ohio supreme court ruled today. Police laser gun overview. Calibration is an essential part of the necessary maintenance.
