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, 1064 nm and 532 nm are the two wavelengths 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.
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.
