Recently, the European Defense Agency (EDA) commissioned a joint study by the Swedish Defense Research Agency (FOI) and the St. Louis-Fade Institute (ISL) to show that laser pointer technology applications can be used as a supplement to existing sensors (sonar) for underwater targets Detection and identification, especially in shallow waters or areas with complex terrain, such as islands and straits.
This study used the relevant hydrological data of the Baltic Sea to simulate the light radar (LIDAR) and laser radar (LADAR), and showed that they can be used for target detection and recognition under harsh underwater working conditions. Target recognition capabilities have a significant positive impact, especially in terms of speed.
Research suggests that laser systems can greatly improve combat capabilities. For example, the airborne laser scanning system can be quickly deployed, can detect, locate and track underwater or surface objects, and can identify large targets. Once the target is found, a surface unmanned boat equipped with a laser surveillance (LGV) system or an unmanned submersible vehicle equipped with an underwater laser scanning (ULS) system can be quickly deployed to further confirm the target information.
Laser target eye. A circle of 10 interacting red laser pointer can synchronize their phases, as shown by the difference between the light and dark rings near the center of the image. However, the use of 20 laser circles will have a 20% chance of causing topological defects, in which the phases of two adjacent lasers are deviated, resulting in the inconspicuous circle between the bright and dark phases.
