摘　　要：为了解决传统水下目标成像系统存在的成像模糊、测距误差高的缺陷,设计了一种水下目标激光成像系统。数据采集卡将驱动信号反馈给激光发射机,发射机射出扇形激光光束,激光束通过发射光学系统以及扫描系统射向水下目标,扫描系统以及接收光学系统对水下目标反射的回波信号进行操作,并将回波信号传输到条纹管探测器的光阴极中,进而获取目标的原始条纹图像,分析了条纹管探测器的激光成像原理,对系统中的激光发射机、光学系统以及扫描系统进行详细说明,并介绍了系统软件实现中VB程序控制信号时序过程以及Matlab图像处理流程。实验结果说明,该系统可获取精确的水下目标图像,并且对水下目标距离进行准确探测,具有较高的成像性能和距离探测性能。In order to solve the problem of imaging ambiguity and high range error in traditional underwater imaging system,therefore design a new system. The data collector feedback the drive signal to laser transmitter,which will emit fan-shaped laser beam. Then the laser beam towards the underwater target through emission and scanning systems.Scanning and receiving systems process the reflected echo signal and transmit the into the photocathode in streak tube detector to obtain the initial target streak image. Analysis the principle of streak tube detector,have a detailed description of the laser transmitter system,optical system and scanning system,and introduce the realization of VB program control signal timing process and Matlab image processing. The experimental results show that the system can obtain accurate underwater target image,has high imaging and distance recognition performances.
