摘要
针对传统的激光距离选通成像系统需要已知距离及精确的激光器传输时间延迟等先决条件,设计并实现了一种基于DSP的激光距离选通成像系统,并对其同步控制方法进行详细地探讨。该方案利用快速DSP控制器完成测距和距离延迟,产生纳秒级的选通脉冲选通ICCD摄像机,有效地实现了距离选通及精确的图像清晰度控制,在无需任何先决条件的情况下,可以获得目标的距离信息和距离选通图像。
To overcome many shortcomings of the conventional LRG imaging system, such as need to know preset range delay and laser inner time delay. A kind of LRG imaging system based on the DSP is designed and realized, and its synchronization control technique is researched.The fast DSP controller is used to accomplish range measurement and range delay and to provide several nanoseconds gated pulse to gate ICCD camera.Range-gating and the precision image definition control can be realized effectively,and the targets＇range information and range-gating image are obtained without any preconditions.
