Laser Modules

Laser Rangefinder - Laser Measurement - Laser Altimeter

Since 2004, we have partnered with UK-based Renishaw as a licensed manufacturer and distributor of their Industrial Laser Module (ILM) in support of the North American Aerospace and Defense Industry.

ILMs use pulsed time-of-flight technology to deliver highly accurate distance and presence information over long or short ranges. The laser module can also use the range to trigger external devices, such as cameras or warning systems. They are used widely by system integrators, especially for military, security and traffic management applications

Use as a Laser Altimeter

The lightweight and compact design of these modules have made them an especially popular choice for integration as an altimeter, incorporated into fixed-wing as well as rotary platforms for both manned and unmanned flight. It has been utilized as part of the Assisted Takeoff and Landing System (ATOL) for the Predator and other UAVs, a tool for crop spraying in the agricultural aviation industry (www.aglasers.com), as well as a standard altimeter for a variety of other aviation applications. While these modules are frequently combined with a cockpit display, they can also work as stand-alone units to give a fully functioning end-user system.

They can be used as a source of data that allows the aircraft control system to calculate:

  • Height (direct from the laser)
  • Rate of descent (by monitoring the height over time)
  • Height during banked maneuvers (by using ranging information from the laser together with information from tilt sensors)
Laser Altimeters for UAV Drone - Predator 
Laser Altimeters for Agriculture Aviation
Laser Altimeters for Fire Fighting Aircraft

Available ILM variants

Standard

The ILM-R (range) variant averages 20 individual range measurements, providing a stable measurement at a rate of approximately 9 Hz.

High repetition

The ILM-HR (high repetition) variant does not average ranges, the range output rate is 400 Hz consisting of 400 individual range measurements.

Trigger Sensor

The ILM-T (trigger) variant is configured to provide a trigger signal to external devices when the range to the target is within a customer defined trigger window.
