Laser Speed Detector Calibration

This has the advantage of making it easier for the officer to tell which vehicle he is getting a.

Laser speed detector calibration.

In a 6 1 decision the supreme court ruled that while the scientific principles underlying the technology of radar or laser. 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. Incorrect calibration or lack of maintenance. Jurisdictions vary regarding how frequently speed measuring devices must be calibrated.

Calibration is an essential part of the necessary maintenance. 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. The quickest way to challenge radar gun evidence is to introduce the calibration records for the device that measured your speed into evidence in court. 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. 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. Generally a certified technician must calibrate the device every 60 days to three years. If the device wasn t.

However the reliability of radar devices depends on whether police kept them in good working order. Split second measurements are the norm for our lasers rendering radar and lidar detectors useless. Manufacturers of the devices recommend calibration before every use but states may require testing and calibration much less frequently. With the introduction of the lti 20 20 truspeed laser speed gun in 2007 laser technology inc accomplished an engineering feat no other laser measurement manufacturer has done design a laser speed device that offered the accuracy and reliability that lti is known for yet be priced so even the smallest of departments could afford to use lidar light detection and ranging technology.

Speed measuring devices generally require regular calibration and maintenance to provide accurate measurements. 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. 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.
