物联网的普遍应用依赖于以不断增长的速度高效地收集、交换和处理信息的能力。这对通信电路和系统的设计提出了巨大的挑战:在设备节点中,无线电通信需要同时实现低功耗、高性能和低成本;在核心数据网络(云)中,海量数据必须以超高吞吐量移动,要求信号链和时钟的高精度和保真度。为了应对这些挑战,本次报告讨论了用于物联网、医疗保健和生物医学应用的超低功率无线电收发器的几种创新架构和电路实现,以及高性能频率产生技术。...
电阻抗成像(Electrical Impedance Tomography, EIT)是一类重要的生物医学成像模型,其基本的物理提法是由生物组织的可测量信息去反演生物体内部的电导率。这类可测量的信息可以是边界上的电流-电位信息,也可能是生物体内部的部分电场(磁场信息)。基于某些生物病变组织电导率的巨大变化,该成像技术在临床的功能成像和结构成像中具有重要的作用,并被用于肺功能临床监测。这类成像问题数...
Hand-held 3D scanning systems are increasingly available on the market from several system manufacturers. These systems are deployed for 3D recording of objects with different size in diverse applicat...
Recently, the diffusion of knowledge on Cultural Heritage (CH) has become an element of primary importance for its valorization. At the same time, the diffusion of surveys based on UAV Unmanned Aerial...
The ODS special conference offers an excellent forum for exchanging information on the status, advances, and future directions in the field of optical data storage and related technologies. The Blu-ra...
Optical instruments are addressing an ever-increasing number of industrial and research applications: imaging and vision, defense, space, telecommunications, transportation, industrial process control...
2017SPIE光学数据存储专题会议(Optical Data Storage 2017:From New Materials to New Systems)。
New research provides scientists looking at single molecules or into deep space a more accurate way to analyze imaging data captured by microscopes, telescopes and other devices.The improved method fo...

We demonstrate by simulation that the superimposed training based channel estimation scheme can achieve similar performance as compared with conventional schemes, without any loss in bandwidth. An ite...
Diffractive diffusers (phase gratings) are routinely used for homogenizing and beam shaping for laser beam applications. Another use for diffractive diffusers is in the reduction of speckle for pico-p...
A new impulse-type display named Local Blinking High Dynamic Range (HDR) LCD System was proposed, which utilized local dimming technology to achieve a local blinking effect that not only suppressed mo...
In this paper, we analyze the impact of analog-to digital convertor (ADC) bandwidth and clipping ratio on the performance of a 1 Gb/s x 15 user CDM-over-fiber-PON (COF PON) system based on 16-QAM modu...
In this paper, we present a reliable architecture for high-capacity fiber-radio system and demonstrate its feasibility. The main trunk of the proposed architecture is a star network with branches comp...
This work demonstrates how electrical driving voltage of a Mach–Zehnder modulator and the bandwidth of electrical low-pass filters (LPFs) affect optical duobinary signals. The fact that a 100% driving...
