现场激光能量计量技术的研究

由于激光能量计传感器的灵敏度与温度条件有关，在温差较大时，有的传感器灵敏度偏差可达到16%，因而在靶场、野外现场温度条件下，现有的激光能量计无法进行准确测试。为了解决这一问题，研制了一种新型的现场激光能量计。在现有激光能量计的基础上，通过选择相对透明、吸收层相对较厚(毫米量级)、热敏面不易损伤的激光吸收材料，对激光能量计内置温度传感器及数字处理电路进行了重新设计，满足了不同温度条件下现场能量测量的需求。

Application of in situ laser energy metrology

As the sensitivity of laser energy meter is dependent on the environmental temperature,the sensitivity deviation could reach 16% in the temperature range of－50℃～70℃. In order to make accurate measurement under the different temperature conditions of open field,a novel laser energy meter for field application was developed. Base on the design of the current laser energy meter,laser materials with better transparence,thicker absorbing layer and thermal sensitivity surface unsusceptible to damage were chosen,the temperature sensor and the digital processing circuit in the energy meter were redesigned to meet the requirements of laser energy metrology in field.
