一种脉冲式半导体激光云高仪的关键技术问题研究
Study on a Pulsed Semiconductor Laser Ceilometer
摘要
Abstract
Cloud,which relates to the phenomenon of water vapor condensation,is not only representative of the atmospheric motion,stability and water vapor,but also an important indicator of weather forecast.Cloud characteristics including its formation,shape,amounts,distribution and evolution can be used to make a further study on the atmosphere.So a new-developed ceilometer based on the pulsed semiconductor laser is introduced in this paper.The whole system is made of three main modules.In the optical module,the designed co-axial optical system can overcome the shortcomings of blind area cloud detection.In electric module,the laser-driven sub-module,low-noise amplifier receiving sub-module and the high-speed signal sampling sub-module are precisely designed.In the data processing module,the wavelet transform algorithm is also described in detail.The finally fashioned ceilometer system can provide the information of cloud heights and cloud optical information,which can fill the gap of pulsed laser cloud detecting technology at home and satisfy the need of weather observation for clouds.关键词
