The Highly Accurate Measuring Method PRT
What is PRT?
PRT is an abbreviation for Pulse Ranging Technology, a direct measuring method for measuring distance. PRT is the most accurate industry-grade distance measuring process.
Pulse ranging technology principle of operation
In this most advanced of all optical measuring methods, a laser diode transmits short pulses of light that are reflected by the target object and then recaptured by a light sensitive receiver element. The power of a single pulse is up to one thousand times more intense than the power of pulses generated by sensors that emit permanent light beams.
The times when the pulse is sent and received are accurately measured.
The exact distance (s) from the object is calculated using the measured values (tL) and the speed of light (c). In modern sensors, this procedure is repeated up to 250,000 times per second.
