Application of Voice Coil Motor Lidar in forest resources monitoring and evaluation. With the rapid development of Lidar Technology, it is widely used in resource exploration, urban planning, agricultural development, hydraulic engineering, land use, Environmental monitoring, traffic communication, earthquake prevention and disaster mitigation, etc. , it provides valuable information for national economy, Social Development and scientific research. 

     In recent years, the central and Southern Academy has also attached great importance to the application of high and new technologies represented by Lidar in the monitoring and evaluation of forest resources, and has used lidar technology to improve the existing monitoring and evaluation system of forest resources in China, to explore the method of annual forest resources to provide information support and decision-making basis for forestry modernization and ecological civilization construction. 

      And in August, just last month, the central Southern Academy invited three high-tech Surveying and mapping enterprises to the state-owned forest farm of Qingyang Lake in Hunan Province to carry out pilot work on the application of high-tech in monitoring and evaluation of forest resources. During the testing process, the three companies have demonstrated various types of lidar, including airborne Lidar, ground-based Lidar, backpack Lidar and RTK-GPS, the field data were collected from coniferous forest and broad-leaved forest in Qingyanghu state-owned forest farm. 

     Speaking of Lidar Technology, Voice Coil Motors have already been used in practical applications. Lidar uses a laser beam to receive light reflected from a distant object, the distance information of distant objects can be obtained by measuring the time of flight of the light beam. However, laser beams are very narrow and they do not scatter, so a single lidar pulse can only sense a very small object. For practical use, lidar sensors have to undergo some form of "scanning" . Most lidar sensors are connected to a drive motor that rotates them, and once the laser is synchronized with the motor's motion, we can tell where the laser is pointing and combine the whole image of the environment ahead. Therefore, the field of view of a lidar depends on the angle at which the motor is rotated. 

       Kunshan with Mao Electronics Co. , Ltd. Independently Research and development, production of voice coil motor, including cylindrical, rectangular, flat, shaft and swing five categories, at present with Mao voice coil motor has penetrated all walks of life.
