Bathymetry Lasers

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 which whose pulses are synchronized, to the water below and using time-of-flight (TOF) laser radar to determine the total round-trip distance.   In this case, one laser is chosen in the near infrared, where water is highly absorbent, and the other is in the visible spectrum where water is highly transparent.  The difference in TOF between the two bathymetry lasers will provide the depth of the body of water. Traditionally, 1064 nm and 532 nm are the two wavelengths used for this application, but it is important to note that most combinations of near-infrared and visible lasers will work.  On this page, you will find a list of all of the bathymetry lasers we offer.
