本文提出了一种测量汽车油管位置的方法。该方法采用平行光投影的光学系统,以高分辨率面阵CCD成像,通过数字信号处理(DSP)系统进行图像采集与处理,处理速度快,可以实现实时处理。在图像处理中,采用合适的边缘检测方法,提高了测量精度。数据处理中采用了最小二乘法拟合曲线,可以精确的拟合出油管像的曲线。与理论曲线相比较,就可以有效地测量油管的位置。

We propose an optical tensor core (OTC) architecture for neural network training. The key computational components of the OTC are the arrayed optical dot-product units (DPUs). The homodyne-detection-based DPUs can conduct the essential computational work
We demonstrate a new scheme for generation of optical frequency comb (OFC) based on cascade modulators, 23 comb lines within 0.5 dB spectral power variation are obtained. An optical finite impulse response (FIR) filter is introduced for suppression of amp
Multilayer black phosphorus (BP) nanoplatelets of different thicknesses were prepared by the liquid phase exfoliation method and deposited onto yttrium aluminum garnet substrates to form saturable absorbers (SAs). These were characterized with respect to
用高速全息术研究了红宝石激光感应击穿的现象。使用全息术代替一般摄影术的优点在于能容易抑制击穿过程中发出的明亮的白光。这种白光在全息照相底片上构成一个非相干的背景,并且不在记录景色的重现象上再现。

In order to obtain large broadband, a novel travelling-wave modulator with nonperiodic domain inversions and ridge structure is proposed. The composite structure is designed to achieve velocity matching between the optical wave and the microwave, to get a
日本大阪府立大学工学部航空条试制成可从远处精确测定空间悬浮物体位置的“激光灯塔”。它是运用半导体激光器和反射镜来确认直升飞机、大型起重机悬挂物之类的空间悬浮移动体的位置,有助于提高作业效率。

Scattering is a huge challenge for microscopic imaging. Indeed, it is difficult to observe target chemicals in scattering media by means of the current Gaussian beam-based stimulated Raman scattering (SRS) microscopy, since the tight focus of the Gaussian
