To function, each TeraRanger Evo requires a yellow backboard.
It provides calibrated distance readings in millimetres and has a range up to 60m, whilst remaining lightweight and small! Instead of laser, TeraRanger Evo 60m uses LED technology. One advantage of this is that it enables the Time-of-Flight sensor to have a “Field of View” so that, rather than measuring distance based on a very small point of light, the sensor measures over an area. At 1m distance the area is approximately 3cm by 3cm. At 10m it is approximately 30cm by 30cm, increasing linearly with range. For many applications this is a significant advantage and provides a more appropriate and stable datastream. Examples include drone flight over vegetation, a robot navigating close to a slatted fence, or irregular shaped objects being detected at high speed.
