Bionic perception, especially temperature-aware, is one of the important issues in soft robots research. This paper presents a method to implant temperature sensor network into soft robot finger by using optical fiber gratings. For avoiding strain disturbance, a dedicated metal tube is designed to package and protect the optical fiber gratings. For implanting the sensors firmly, a solution using two kinds of adhesive is proposed. The prototype is calibrated in high precision temperature bath and then measured under different temperatures and different bending conditions, respectively. The experimental results are compared with electronic temperature sensor (PT100 thermal resistance), which verifies the accuracy and repeatability of the design. With the dedicated coating and adhesive solution, the proposed temperature sensor network is suitable for implanting into soft robots for the temperature-aware ability.

对纳秒级宽带KrF激光脉冲的时间整形进行了研究。采用受激布里渊散射(SBS)脉冲压缩KrF激光获得短脉冲,通过脉冲堆积获得KrF激光时间整形脉冲。利用激光放大器对整形脉冲进行放大,对KrF激光整形脉冲的形状影响较大。通过对放大前整形脉冲形状的调整,在放大后可以得到所需形状的整形脉冲,一次放大能量输出可达50 mJ,二次放大能量输出可达300 mJ。理论分析与实验结果一致。研究表明,短脉冲堆积和放大器放大的组合方案具有较强的整形能力。

光源的位置和色品影响景物在摄像机中的成像,耀斑和阴影的出现使一般的分割算法得不到理想的分割结果。本文根据双色反射模型将图像分解成两个本征图像——本色图像(matte image)和耀斑图像(highlighit image)。本色图像是去掉耀斑影响的图像,反映了景物本身的不变性,不受外部因素(光源的位置和色品)的影响。而耀斑图像是只含有耀斑的图像,恰反映了外部因素的影响。并提供景物形状的信息。
