采用阵列传感器测量光斑方法在实际使用中非常有效,但固定阵列在设计中存在一些困难,通过旋转系统的设计,成功研制出大单元数的阵列光斑测量仪.旋转系统本身的特性要求机械和电路设计采用特殊的结构以解决系统的稳定性.给出了系统研制的设计思想,实现方法及实验测量结果.

Using the traditional technique to measure laser facula with a detector array, the array should be large enough if the facula has a large size. Thus large amount of detectors are needed which increase the cost. The design of rotational device of array detector makes it possible for measuring laser facula with high spatial resolution and low cost. The main idea is to rotate a linear array of detectors to carry out the facula measurement in the scanned area. The developing routine of the device and its measurement result is presented.
