1.Product Introduction

  PM Cache is one of the high-energy lidar products, belonging to the high-power millijoule lidar. In the same weather conditions, compared with micropulse lidar, it has better time resolution and signal-to-noise ratio, and the monitoring period is shortened by about 10 times. It can provide rapid scanning and rapid image of atmospheric aerosols. The detection altitude and data validity in weather are significantly improved compared with micro-pulse lidar.

  Traditional high-energy lidars are bulky and heavy, which limits their use scenarios. AVORS Technology’s PM Cache lidar, after optimized design of components, is currently the largest power lidar with smaller size and weight on the market. It is suitable for vehicle-mounted mobile laboratories and field observations, and plays an important role in the development of a new generation of high-power lidar technology.
