摘　　要：提出了利用双光束分光光度和扩束系统相结合方法实现光学元件透射率全口径检测,建立了相应的检测系统,通过实验对系统的透射率检测精度进行分析和验证。结果表明,系统透射率检测精度优于±0.05%,并具有很好的重复性,能够用于ICF系统中大口径光学元件透射率的高精度、全口径检测。The transmissivity of optics is one of the important properties for high power output of laser system.This paper proposes a new method to measure transmissivity of large aperture otpics of the ICF system.A measurement system is constructed,and its accuracy and repeatability are analyzed by the cavity measurement for 10 times.The experimental results show that the transmissivity accuracy of the system is 0.1%,and the repeatability is better than 0.08%.In the other hand,large aperture optics with and without coatings are measured by the system to compared with the result measured by lambda 900.The results show that the repeatability of this system is better than that of lambda 900,because the result of full aperture measurement of transmissivity can not be affected by the thickness of coating.
