激光预警接收器的一种改进方案
Modified Version for Laser Warning Receives
【摘要】 提出了一种新的激光预警接收器的设计方案.其中设计制作了一种小型实心迈克尔逊干涉装置,它能使进入该系统的除激光之外的所有杂散光不产生干涉,能对其干扰产生抑制作用;设计了一种信号光波面变换系统,使该系统形成的迈克尔逊等倾干涉图的结构变的极简单、信号光能量分布很集中,能有效地提高信噪比、简化光电转换接收系统;设计了一种基于瞬态峰值检测的光电转换集成电路,能显著提高测窄脉冲激光时的信噪比,使系统能有效地监测其波长在可见光区和近红外区的各种激光信号.
【Abstract】 The new designed project of laser forewarning acceptor is proposed.Thereinto a small solid Michelson Interferometer is devised which can lead to no interference to all the stray light except for laser beam and have the depressing effects on the stray light.And the Wavefront-Transforming system of signal light is also designed which make the Interferograms very simple and cause the Energy centralization of the signal light and the promotion of signal-to-noise ratio and simplification of the photoelectricity switch system.The photoelectricity switch IC used to measure the peak wavelengh can greatly promote the signal-to-noise ratio of the measured narrow pulse laser and detect the near infrared laser signal and visible wavelength laser signal.
【Key words】 laser warning receiver; tunable lasing light emitter; laser receiving antenna; improved solid Michelson interferometer; linear array of photoelectric diode which can test peak value;
