灰度信号 meaning in Chinese
grey scale signal
Examples
- We invented the method of transmitting the gradation data by dma , after we analyzed different circuit of control and transmit gradation data . we analyzed different circuit to achieve gradation , different schemes to drive led , and brought out the mechanism scheme of the new system . we discussed the functions of hardware system , software system , and mechanism system in detail
论文第三章讨论了环场显示系统的电路和机械设计方案，分析、比较了不同的驱动电路和信号传送方式，提出了利用cpld并行dma传送灰度信号的方法，分析比较了不同灰度实现方案、不同led驱动方式，讨论了电路软件系统实现方案，提出了系统样机的机构方案。 - It has been a long time on blood velocity measurement [ 9 ] of this type . there are many methods to obtain the windows . but the intensity signal obtained from the windows is n ' t accuray of some methods or the real time property is not very good of others
用相关算法时，血液流速是血管上两窗口间的距离除以血液流过两窗口所用时间，时间用两窗口血液灰度信号最大相关计算得到，微循环血液流速测量的研究已经有很长的时间[ 9 ] ，其中血管窗口的选取现在有多种方法，但现有的方法要么窗口取得不准确[ 9 ] ，要么实时性较差。 - 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。
