光学层析成像传感器结构由发光元件与感光元件组成,对重建图像的精度有重要作用。鉴于此,对扇形发光与感光元件的分布进行了优化研究。首先,将发光与感光元件的位置信息构建为角度向量。然后,引入灵敏场均匀性参数作为该结构的评价指标,并通过仿真实验验证了该指标的可靠性。最后,基于遗传算法对传感器结构进行优化,将角度向量作为优化对象来确定传感器结构,并将灵敏场均匀性参数作为适应度函数。在所获得的优化结构中,发光与感光单元分布不均匀,均匀性参数为0.288。多种具体分布的图像重建实验表明,该传感器优化结构在重建精度、图像准确性和噪声等方面均优于传统分布和随机分布。

The characterisation of a small sonochemical reactor has been performed using electrochemical, luminescent and photographic techniques.
