Laser Distance Sensors Can Be Used as Laser Altimeters
The AR3000 Has Been Used by NASA and UAV Manufacturers to Create Laser Altimeters
Un-manned Autonomous Vehicle (UAV) projects depend on sensors to provide spatial information for route planning and crash avoidance. A developer of UAVs selected AR3000 distance measurement sensors to measure the height above the ground, whether it was the landing strip, grass or trees.
A dual-sensor system can be used to give improved accuracy at both short range and long range distances. A 10 mrad version can be used for measuring between 0 – 50 meters, and a 2 mrad version can be used for 50 – 300 meters. NASA has also used Acuity’s products to create laser altimeters for their landers.
AS2100 Accurate Distance Sensor
The AS2100 is a highly accurate laser distance sensor that is designed to work well outdoors, in bright lights, and even on difficult targets such as hot or dark surfaces. With the ability to take accurate measurements (± 1 mm) from distances up to 500 meters away, and a measurement frequency of up to 250 Hz, it is the perfect laser for a wide range of applications.
AR2700 High-Speed Long Range Sensor
Acuity Laser’s ultra-compact rangefinder model. This eye-safe rangefinder has a measurement frequency of up to 40 kHz and can measure distances to natural targets up to 70 meters away or to retroreflective targets 270 meters away. This laser is best for applications that demand high sampling rates.
AR3000 Distance Measurement Sensor
AR3000 distance measurement sensors are Acuity’s longest-range models. Ideal for measuring positions of cranes and trolleys, the time-of-flight sensor can measure up to 300 meters to natural surfaces and up to 3,000 meters when using a retroreflective target.
