本文在LabVIEW和NI-IMAQ Vision软件平台下，利用通用图像采集卡开发一种图像实时采集处理虚拟仪器系统。通过调用动态链接库驱动通用图像采集卡完成图像采集，采集图像的帧速率达到25帧每秒。利用NI-IMAQ Vision视频处理模块，进行图像处理，以完成光电探测器的标定。该系统具有灵活性强、可靠性高、性价比高等优点。(In LabVIEW and NI-IMAQ Vision software platform, the use of a common frame grabber to develop a real time image acquisition and processing the virtual instrument system. Drive general-purpose image acquisition card by calling the dynamic link library complete image acquisition, the acquisition of the image frame rate up to 25 per second. NI-IMAQ Vision video processing module, image processing, in order to complete the calibration of the photodetector. The system has the flexibility, high reliability, high cost.)

labview温度计系列实验，数据采集与回放系统(LabVIEW thermometer series experiment Data acquisition and playback system)

基于labview的频谱分析，简单的fft快速傅里叶变换(Spectrum analysis based on LabVIEW ， Simple FFT fast Fourier transform )

说明：  虚拟示波器的设计， 基于LabVIEW的虚拟示波器设计 (Virtual Oscilloscope)

说明：  labview编写串口通讯实例，基于ModBus协议，使用串口通讯，与电机驱动器通讯，实现信号写入与读取，从而控制电机(LabVIEW serial communication, signal writing and reading)

说明：  控制转台旋转角度情况下，7路光功率计同时探测光强变化，联谊和thorlabs设备，需导入子vi。(Under the condition of controlling the rotation Angle of the turntable, the 7-channel optical power meter can simultaneously detect the change of light intensity.)

用于xmodbus方式通讯。使用labview编制CRC16-XMODEM.vi(Kaubamaja for Xmodbus communication. Using LabVIEW establishment.CRC16-XMODEM.vi)

说明：  本代码编制测距传感器的串口通讯接口VI；通过波形图表显示连续读取的测距-时间曲线，并将有效测量范围外的数据滤除。(This code compiles the serial communication interface VI of ranging sensor, displays the continuous read ranging-time curve through waveform chart, and filters out the data outside the effective measurement range.)

一个简单数据的采集和显示的程序，可适用于多种通讯协议，适合初学者学习(A simple data acquisition and display program, suitable for a variety of communication protocols, for beginners to learn)

通过一个NI USB-6501 便携式数字I/O设备，控制一个步进转台的旋转。可选择旋转方向，并以5°为单位旋转。(NI USB-6501 via a portable digital I/O devices, control the rotation of a stepping turntable. Alternatively the direction of rotation, and 5 units of rotation.)
