- And as i check my iighthouse gauges . .
在查看灯塔的测量仪时. . - And as i check my iighthouse gauges
在查看灯塔的测量仪时 - The time - domain measure technique of vector network analyzers base on inverse chirp - z transform
逆变换矢量网络分析仪时域测量技术 - Two wedge interferometers are designed that the thickness of one is higher than the other . so when the incident coherent light through the interferometers can acquire two fringe patterns which having space shift , but the incident incoherent light only result in consistent intensity signal . through a differentiating amplifier , two signals subtract which can eliminate noise of background and result in higher contrast ratio fringe signals . this method largely improves the system and the ability of detection . the spacing of line fringes is a function of incident laser wavelength , by analyzing , we can extract the wavelength of incident laser . the optical unit analyzing and results also simulated with matlab
当背景光入射时，直接穿过干涉仪，仅发生强度的衰减，在两个探测平面上产生幅度基本一致的灰度信号，通过差分放大器，相消为零，从而抑制了背景干扰。当激光信号入射，穿过干涉仪时受到调制，在探测平面上产生干涉条纹。通过所设计的存在平均厚度差的双楔形干涉仪，两路干涉条纹图案出现相对移位：在两个探测平面对应的位置上，一路出现亮纹，另一路出现暗纹。 - Due to too much short sustained time duration of oscillation for the blades and too wide distribution of oscillation frequency over the audio frequency range , a procedure of variable gate frequency measurement has been applied to the design of frequency measuring instrument with a micro - - controller unit ( mcu ) as its core . this procedure features a high precision and rapid speed
由于叶片振动持续时间很短，且振动频率在音频范围之内分布较广，故在设计以单片机为核心的测频仪时采用了变闸门测频法，该方法具有精度高、速度快的优点。
