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.
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.
