介绍了一套十分适合应用于准连续激光物理实验的变换装置。该套装置不但可以将热电偶激光功率计输出的直流型模拟电压量变换成计数脉冲输出
还可以对光离子引起的、探测器给出的脉冲型模拟电压量进行累计变换。经过详细的模拟测试得知它变换激光功率的积分线性≤±0.015%
变换光离子脉冲信号的积分线性≤±0.23%。以上测试结果表明该套变换装置已经满足了一般激光物理实验的精度要求。
A new application of V-F converter for quasi-continuum laser physics experiment is described. It is used to convert not only direct current analog voltage outputted by powermeter
but also pulse analog voltage outputted by particle detector. Tests have demonstrated that linearity of the conversion reached ±0.015% for 10—1000mV of direct current analog voltage and ±0.23% for 400—7800mV of pulsed analog voltage. The accuracy satisfies experimental requirement.
