scan frequency meaning in English
扫描频率
Examples
- Frame scan frequency
帧扫描频率 - 3 . scan frequency is over 200hz : using over 200hz frame scan frequency will have good vision effect
3扫描场频大于200赫兹：使用帧扫描频率200hz以上，有很好的视觉效果，人肉眼几乎 - Scanning frequency has reached over 240hz which makes the menu stable and no flicker . in using actually , we use vidicon shoot the display screen . and then we can observe the photo is very clear from the vidicon
2扫描场频达到了240hz以上，画面稳定无闪烁，在实际应用中，用摄像机拍摄显示屏，摄像机中观测到的图象十分清晰，没有同步滚动条，若现场有电视转播，显示屏不会影响转播画面的质量。 - By the advantage of high precision , strong anti - interference ability , long lifespan , etc , grating scale is the chief sensor in displacement measurement . however , as is restricted by the beam path structure , the scan frequency of the scaning circuit , etc , the maximum available measuring speed has a inverse proportion relationship to the measuring pace of a single grating scale
光栅尺具有精度高、抗干扰能力强、寿命长等优点,成为微纳米位移测量的主要工具,但由于受光路结构及信号检测电路扫描频率等因素的限制,单个光栅尺测量的最大允许移动速度与其测量步距成反比。
