马赫-曾德尔干涉仪(MZI)具有光学能量利用率高、便于视场展宽等优点,在光学滤波、鉴频等方面具有广泛的应用.然而,在实际应用中MZI频谱会受到各种因素的影响而导致性能下降.从理论上导出了在考虑入射光发散角2θ0和谱宽?ν的影响下,MZI干涉频谱的理论表达式,并定量分析了其对MZI频谱的影响.结果表明:MZI的光程差l越大,其频谱受?ν的影响越显著,l与入射光波长λ比值越大,其频谱受θ0的影响越显著;当λ=355 nm,l=3 cm时(第1种情形),?ν=10 GHz和θ0=4.5 mrad将分别使条纹对比
在多用户光码分多址(OCDMA)传输系统中,多用户干扰(MAI)严重影响系统传输性能.针对系统中多用户干扰来源于各用户码字不完全正交的特点,采用码字的自、互相关函数表达接收信号与系统损伤,引入将多用户干扰看作可重构的“有效信息”的新思路,提出了一种基于数字信号处理技术的串行反馈干扰抑制算法.搭建了2用户同步接入频谱幅度编码光码分多址(SAC-OCDMA)传输系统仿真平台,验证了该算法抑制多用户干扰的有效性.仿真结果表明:相较于光阈值器件,采用串行反馈干扰抑制算法抑制多用户干扰的效果更好,系统传输性能的改善

Poroelasticity of cytoplasm is a rate-and size-dependent biphasic material behavior that reflects the normal activities and pathological states of cells,mainly caused by the migration of fluid molecules and the deformation of porous solid skeleton(protein
In this paper,we derive mathematical formulas for the skin friction coefficient in wall-bounded turbulence based on the Reynolds averaged streamwise momentum equation and the total stress.Specifically,with a theoretical or empirical relation of the total
Nature and technology often adopt structures that can be described as tubular helical assemblies.However,the role and mechanisms of these structures remain elusive.In this paper,we study the mechanical response under compression and extension of a tubular
针对过冷云分布的探测,设计了一种近红外机载偏振同轴微脉冲激光雷达系统.该系统采用波长1550 nm激光激励,可有效减少云中小尺度气溶胶粒子的消光,从而提高大尺度云粒子的探测距离和效率.通过非球形粒子的退偏比来甄别云粒子相态,同时提出了云含水量的激光雷达反演算法,并结合机载温度数据和对流层特征,反演过冷云的空间分布.基于标准大气模型和机载仪器的云粒子谱数据,仿真分析了不同激励波长偏振微脉冲激光雷达在两种对流层云中的探测性能,结果表明下层云中的探测距离约为1.1 km,而上层云中的探测距离可达1.5 km.
