Distance Measurement with Pulse Ranging Technology (PRT)
Advanced process developed for industrial applications
Pulse Ranging Technology (PRT)
In the direct Pulse Ranging Technology process, a laser diode transmits short pulses of light, which are reflected on the target object and then recaptured by a light-sensitive receiver element. This process exceeds all previous methods – in particular, frequently used phase correlation and analog chip-based processes. These methods only deliver satisfactory results with a maximum phase shift of 360°, and show a high dependency on ambient conditions such as extraneous light, changing measuring objectives and interaction with other industrial sensor systems.
The superiority of Pulse Ranging Technology is due to the transmission of faint light pulses containing energy up to a thousand times more intense than sensors emitting permanent light beams. The process always achieves accurate, reliable, unambiguous, and reproducible results regardless of ambient conditions such as surface quality, color or prevalent extraneous light.
