采用动电位极化曲线和电化学阻抗谱研究了激光选区熔化成形CP-Ti和Ti-5%TiN复合材料在人工模拟体液Hank溶液中的腐蚀性能,结果表明:激光选区熔化成形CP-Ti主要由针状α-Ti相组成,加入的TiN颗粒不仅可以与钛基体形成良好的界面结合,还可以细化α-Ti晶粒并产生更多的晶界;在Hank溶液中,激光选区熔化成形Ti-5%TiN复合材料具有比激光选区熔化成形CP-Ti更好的耐腐蚀性能,这是因为作为微阴极的TiN颗粒均匀地分布在钛基体内,可以加速钛基体的阳极溶解过程,使Ti-5%TiN复合材料能够优先进
We propose and experimentally validate an optical true time delay beamforming scheme with straightforward integration into hybrid optical/millimeter (mm)-wave access networks. In the proposed approach, the most complex functions, including the beamforming
激光辐射在地球至宇宙间通道内大气衰减的测量,是在实验上遇到困难的问题。我们研制了能在HF和DF激光波长下作这些测量的以地球为基地的系统。将介绍几条激光谱线的实验结果。吸收测量系统的中心是接近量子噪声极限的光学外差辐射计。

Scanner color management is one of the key techniques for color reproduction in information optics. A new scanner color management model is presented based on analyzing rendering principle of scanning objects. In this model, a standard color target is tak
A high power narrow-linewidth nanosecond all-fiber laser based on the master oscillator power amplifier (MOPA) configuration is demonstrated. A pulsed seed with high repetition rate of 10 MHz was generated by modulating a continuous-wave (CW) single-frequ
本文首次报道了40mm孔径Nd:YAG片状激光器的激光特性.理论分析表明这类器件可望获得千瓦级激光平均功率.
深度学习在人脸识别的研究和应用中取得一定成效,但因计算量大且耗时,不适用于小型嵌入式设备。基于融合梯度特征的轻量级卷积神经网络SqueezeNet提取人脸特征,既能保证该网络模型适用于内存相对小的嵌入式设备,又能保证获得的人脸特征对不同光照更具鲁棒性。实验结果表明,将8×8分块图像中提取的一阶梯度特征,与轻量级卷积神经网络提取的全局特征相融合的人脸识别算法,在LFW数据集中识别率可达97.28%,
Experimental implementations of continuous optical time domain Fourier transformation based on time lenses and optical orthogonal frequency-division multiplexing (OFDM) system are carried out. Such a system is verified through 100-km transmission of 10-Gb
This Letter is concerned with the influence of polarization on the damage performance of type I doubler potassium dihydrogen phosphate crystals grown by the conventional growth method under 532 nm pulse irradiation. Pinpoint density (ppd) and the size dis
