LED Illumination

Instead of using laser emitters we use Infrared LED technology. This brings a number of important benefits.



Eye-safety: TeraRanger sensors remain eye-safe in all conditions, with no need for Laser Class 1 safety precautions!



Field-of-View: Rather than measuring a very small point, we can allow the emitted light to spread and form a Field-of-View. In many applications, this can be a distinct advantage. Imagine a sensor trying to detect a tree. With a laser, you might detect the leaves, or pass through the gaps and detect something much further away. In a robotics safety or anti-collision situation, this could spell disaster. With TeraRanger technology you are far more likely to detect the hazard you want to avoid. Generally, at 1m to the target, a TeraRanger One sensor is measuring an area approximately 4cm by 4cm.



Power consumption: Compared to some laser devices, LED’s consume far less power; something all users relying on battery-power will enjoy.
