距离选通激光主动成像可在能见度受限条件下有效克服大气后向散射和背景干扰，得到被观测目标的高对比度图像。可视空间深度能够体现实际成像的景物范围，对评价图像质量和其所在的空间位置具有重要意义。阐述了距离选通成像技术高速门控成像的原理及关键器件的选型要求，介绍了可视空间深度的相关概念，通过实验得到了可视空间深度的实际测量值，验证了可视空间深度随激光脉冲宽度的变化规律，并与理论计算值进行了比较分析。

Range-gated laser active imaging could effectively overcome atmospheric back-scattering and background interference in low visibility, resulting in high-contrast images of the observed target. The visual spatial depth can reflect the actual imaging range, which has great significance in the evaluation of image quality and its spatial location. The describes high-speed gated imaging principle and key devices selection requirements of range-gated imaging technique and introduces the concept of visual spatial depth. The actual measurement values of visual spatial depth have been obtained by experiments to verify the visual spatial depth with the variation of the laser pulse width, and compare with the calculated values.
