Differential-Absorption LiDAR (DAL) is an active remote sensing technology for providing detailed information about the surfaces of the Earth. It can be used to measure the topography of the land as well as other environmental characteristics, such as vegetation. DAL11B and DAL11C are two different types of DAL systems. In this article, the application field and working principle of DAL11(BC) will be explored.

DAL11 (B & C) systems are used primarily for mapping small-scale terrain features. The systems use a dynamic ranging technique which allows the surveyor to take measurements from multiple points in a much shorter time than traditional surveying techniques. This makes DAL11 (B & C) systems ideal for mapping small-scale features on a landscape, such as vegetation, in detail. The system can also be used for applications such as determining the topography of a golf course, measuring surface water features, locating underground structures, and examining the erosion of cliffsides.

The working principle of a DAL11(B & C) system is quite simple. A laser is emitted from the instrument and is focused on the subject matter being measured. The laser beam then reflects off of the target and is collected by the instrument. By computing the time-delay between the original emission and the returning signal, the system is able to calculate the distance between the instrument and the target. By repeating this process from different points, the system can construct a map of the surveyed area.

In addition to the procedural benefits of the DAL11B & C systems, these systems also provide very detailed images of the terrain, which can be used to construct 3D virtual models of the landscape. This can be an invaluable asset for agriculture, engineering, and other industries. For example, the system can be used to measure soil moisture content and crop growth, as well as to determine the exact topography of an area. This information can be used for flood prevention, geological studies, and a variety of other environmental studies.

The DAL11B & C systems also provide a greater range of coverage than traditional surveying systems. The larger range allows for more precise measurements, as well as allowing for measurements to be taken in areas that would not be accessible to surveyors. The systems also provide a more detailed image of the landscape, with greater resolution than what traditional surveyors are able to achieve.

The DAL11B & C systems have become increasingly popular in recent years, due to their ability to provide more accurate and detailed information than traditional surveying methods. They have become invaluable tools in a variety of industries, providing detailed information that can be used for a wide range of applications. The systems provide cost-savings in terms of reduction in the need for personnel, as well as eliminating the need for manual surveying.
