采用热弹性模型, 对光学薄片点胶过程进行了有限元分析。对点胶后影响工件面形变化(Δp)的工艺参数进行了优化。研究结果表明, 对于光学薄片(直径为100 mm, 厚度为2 mm), 宜选择具有高弹性模量和低热膨胀系数的薄底板材料, 且胶点的半径、个数及弹性模量越小, Δp越小; 胶点位置应该避开高Δp区域; 胶点的热膨胀系数对Δp的影响较小。

提出了一种电压温度双参量光纤传感器.在理论上分析了从一个敏感晶体上分离出温度、电压两种信息的可能性:石英晶体作为敏感元件.通过合理安排传感头中各部件.传感器同时输出两路信号:一路是包含Pockels效应的电压信号;一路是石英晶体旋光效应的信号.由于旋光效应与温度有关.这路信号用来反映传感头光路上的温度信息.实验获得理论所预期的结果.从而只使用一个传感头就可以同时测量电压与温度.给出了实验装置.结果
距离测量作为几何量测量关键共性基础技术之一,在科学研究、高端装备制造及空间探测等领域有重要应用。新兴的双光梳绝对测距技术充分发挥了光学频率梳的时域超短脉冲和频域高分辨特性,能实现大范围、高精度、高测速的绝对距离测量。首先,在简要阐述双光梳基本原理的基础上,着重介绍了双光梳飞行时间法测距和相位法测距的研究进展;然后,介绍了双光梳测距技术的功能拓展、仪器化进程及应用实例;最后,对双光梳测距的发展进行了展望。

The direct replication of W/Si supermirrors is investigated systematically. W/Si supermirrors are fabricated by direct current (DC) magnetron sputtering technology. After deposition, the supermirrors are replicated from the supersmooth mandrels onto ordin
Mode distortion induced by stimulated Raman scattering (SRS) has become a new obstacle for the further development of high-power fiber lasers with high beam quality. Here, an approach for effective suppression of the SRS-induced mode distortion in high-po
We propose a continuous-wave (CW) middle infrared (MIR) and long infrared (LIR) dual-band laser for the calibration and effect research of infrared detecting and imaging systems. A total output power of 18 W is achieved by the proposed dual-band laser thr
