摘要
用激光回波脉冲控制电子快门来操纵摄像机的曝光时间,是抑制背景噪声的一种有效方法。 提出了异步触发摄像机电子快门的预测方法,并将它应用在激光光斑的捕捉和测量中,提高了光斑图像的信噪比。该方法适用于测量经过编码后的远距离激光脉冲光斑,为应用电视摄像机捕捉有规律的瞬态存在的目标提供了一个途径。
Steering exposure time of a camera through control electron shutter with laser echo pulse is an effective method for inhibiting background noise. A prediction method asynchronously triggering electron shutter of a camera is proposed, and it is applied to acquisition measurement of laser spot, the signal-noise ratio of the spot image is improved. The method is suitable for measurement of the encoded remote laser pulse spot and provided a approach for application of TV camera to acquisition of the regularly transient targets.
