为了提高推扫(Push-Broom)成像系统的信噪比(SNR), 提出了一种可以在模拟域下实现时间延迟积分(Time-Delay-Integration, TDI)功能的CMOS-APS读出电路。区别于以往的数字域算法TDI, 在模拟域下累加可以获得更小的噪声和较慢的ADC读出速率。读出电路主要由像素阵列、TDI累加阵列、电荷放大器、S

An intracavity frequency-doubled vertical external cavity surface emitting laser (VECSEL) with green light is demonstrated. The fundamental frequency laser cavity consists of a distributed Bragg reflector (DBR) of the gain chip and an external mirror. A 1
The importance to industry of non-contact bearings is growing rapidly as the demand for highspeed and high-precision manufacturing equipment increases. As a recently developed non-contact technology, near-field acoustic levitation (NFAL) has drawn much at
研究了复杂背景环境下抗遮挡和抗干扰的目标检测跟踪技术。提出了基于轨迹预测关联的红外/可见光混合决策检测跟踪算法,开发了基于VPX总线架构的FPGA+DSP硬件模块和关键软件模块。结果表明,该方法综合利用红外与可见光两种图像的优势信息检测跟踪同一目标,能够有效地解决目标检测跟踪过程中抗遮挡和抗干扰的问题。
In this paper, a novel liquid refractive index (RI) sensor based on fused tapered photonic crystal fiber (PCF) is proposed. It is fabricated by fusing and tapering a section of PCF which is spliced with two single-mode fibers (SMFs). Due to the fused bico

T矩阵法适合用来研究微粒尺寸与入射光波长相近时系统中光镊的捕获力。T 矩阵法只取决于散射微粒的形状、尺寸大小、折射率及微粒在坐标系中的位置,而不受入射场约束。主要简述了T 矩阵法基本原理和计算,综述了光镊中单个微粒、两个微粒及两个以上微粒捕获力和力矩的计算方法,并对T 矩阵法在光镊中的应用前景做了分析。
The metal aluminum (Al) is widely used because it has high reflectivity from the ultraviolet to the infrared band. But the new deposited Al films is exposed to the atmosphere, it forms transparent Al2O3 films on its surface at once. In this letter, the Al
为了实现大容量光纤通信,正孜孜不倦地研究远距离无中继、高速调制等传输技术,同时,由于从光纤端面反回的光可造成激光光源的振荡不稳定,所以需要研制形成单向光路的光隔离器。特别是最近长波(1.3微米、1.55微米),单色性极好的分布反馈激光器已达到实际应用,对小型、性能优良且价格便宜的光隔离器的要求便立即髙涨。
