incoherent light meaning in Chinese
不相干光
非相干光
Examples
- As with incoherent light one then adds irradiances rather than amplitudes .
就和非相干光的情况一样，这时是将辐照度相加而不是把振幅相加。 - Spatial incoherent light
空间非相干光 - Clear three - dimensional images have been successfully reconstructed by this method . the recording and reconstruction can be performed with incoherent light
利用该方法可以重构清晰的三维立体像，而且可利用非相干光记录和再现。 - In the last part , we give the theoretical deduction and the experiment setup of the two self reference image holograms of the original objects illuminated by incoherent light , the principle is alike with the former
基本原理与采用相干光时相同，同时也给出了实验装置，推导出全息图再现像的位置，展示了根据再现像拍摄出的黑白照片。 - 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。
