摘要： 激光探测设备被广泛应用于精确瞄准、捕获、跟踪系统中，在其投入使用前，需要进行多次仿真测试。激光目标模拟器是激光探测设备仿真测试时使用的重要仿真设备，但是具有体积大、不易搬运的特点。本文设计了一种激光目标模拟器现场功率校准装置。该校准装置由光阑、聚焦光学系统、能量探测单元、时域探测单元、二维位移机构、微型转台和控制软件等组成。校准装置可现场对1.064μm、峰值功率范围(10-5～10-1)W的激光目标模拟器功率稳定性及均匀性进行准确、快速校准，功率稳定性及均匀性测量不确定度均小于8%（k=2），从而为激光目标模拟器提供计量保障。

Abstract: Laser detection equipment is widely used in precision pointing,acquisition and tracking systems.Many simulation tests are needed before it is put into use.Laser target simulator is a important simulation equipment used in laser detection equipment simulation test,but it has the characteristics of large size and difficult to carry.In this paper,a field power calibration device for laser target simulator is designed,which is composed of optical aperture,focusing optical system ,energy detection unit ,time domain detection unit,two-dimensional displacement mechanism,miniature turntable and control software.The calibration device can accurately and quickly calibrate the power stability and uniformity of the laser target simulator with 1.064μm and a peak power range of 10-5 W～10-1W.The uncertainty of power stability and uniformity measurement is less than 8%.Thus provides measurement guarantee for laser target simulator.

Key words: Laser target simulator, Power calibration device, Field calibration technique
