Remote Sensing & Imaging Lasers
What are Remote Sensing & Imaging Lasers?
Remote sensing and imaging lasers are widely employed in the defense, aerospace, industrial and other sectors for various applications. These pulsed lasers play a crucial role in target detection and tracking systems, supporting reconnaissance and surveillance missions. They enable accurate mapping of terrains, assist in missile defense systems, and enhance situational awareness by providing real-time data about the environment. Additionally, they contribute to navigation and guidance systems, offering precise positioning, obstacle detection, and landing capabilities. Overall, remote sensing and imaging lasers provide advanced capabilities for defense and aerospace markets, enhancing operational effectiveness and ensuring mission success.
Remote Sensing & Imaging Applications
Bathymetry Lasers: Laser bathymetry takes advantage of the absorption properties of water to map the depths of large bodies of water including lakes and oceans from a passing airplane. This is achieved by shooting two different pulsed lasers whose pulses are synchronized, to the water below and using time-of-flight (TOF) laser radar to determine the total round-trip distance. Traditionally, high pulse energy lasers, one outputting 1064 nm and one with 532 nm are used for this application.
LIDAR Lasers: LIDAR laser sources are the key component within LIDAR systems, the optical analog to traditional radar. Because optical frequencies are much higher than their radio wave counterparts, lasers allow for much higher bandwidth signals and therefore much higher resolution detection. Typically, short-pulsed lasers are utilized for stationary targets, and single-frequency lasers are utilized for measuring the speed of moving objects. Higher powers allow for longer detection distances.
3D Scanning Lasers: Similar to laser radar, 3D laser scanning is a non-contact, non-destructive technology that digitally captures the shape of objects creating a point cloud of data from the surface of an object. The primary differentiator between laser radar and 3D scanning is the distance from the target. In this application, the laser is typically only few inches from the object under investigation. Both pulsed and CW lasers can be used, and typically visible wavelengths, where shorter wavelengths allow for higher precision/resolution.
