SeaTrepid offers clients LIDAR (Light Detection and Ranging) systems. LIDAR is an optical remote sensing technology that measures properties of scattered light to find range and/or other information of a distant target. The prevalent method to determine distance to an object or surface is to use laser pulses. Like the similar radar technology, which uses radio waves, which is light that is not in the visible spectrum, the range to an object is determined by measuring the time delay between transmission of a pulse and detection of the reflected signal. The term laser radar is also in use but is misleading because it uses laser light and not the radio waves that are the basis of conventional radar.
