为了准确测量高能激光系统远场到靶总能量和功率密度时空分布等参数,本文提出了量热吸收法和光电探测阵列法相结合的复合式测量方法。该方法由热吸收体测量入射激光的总能量,由光电探测阵列测量光斑的时空分布。研制了用于大面积、长脉冲近红外高能激光测量的复合式光斑时空分布探测器。探测器主要由石墨热吸收体、近红外探测器阵列、测温单元和信号处理单元等组成,有效测量光斑面积达到22 cm22 cm,光斑测量空间分辨力为1.1 cm,时间分辨力为20 ms。该测量系统同时兼顾了光电探测阵列法的高时空分辨能力和量热吸收法的低测量不确定度等优点,适合于高能量、大面积近红外高能激光光斑参数的综合测量,并已成功应用于外场实验。
To measure the beam profile and power density distribution of a far field target in high energy system performance evaluation
a high energy laser detection method is proposed by combining photoelectric and calorimetric methods. In the method
the total energy of incident laser is measured by an absorber and the spatial and temporal distribution of laser profile measured by a photoelectric detector. The detector is developed
which is consisted of a graphite calorimeter
an InGaAs photoelectric detector array
a temperature and voltage amplifier
an analog to digital converter and a signal processor. The system with an effective sensitive area of 22 cm22 cm can offer a spatial resolution of 1.1 cm
a temporal resolution of 20 ms
and a low energy measurement uncertainty less than 10%.With the higher temporal resolution and lower energy measurement uncertainty
the system is suitable for high energy and large area near-infrared laser beam measurement.It has been used in field experiments successfully.
