A data acquisition and processing system of visible spectrum based on virtual instrument was designed. The sensitivity of the system was increased by adding three output channels of RGB of the color linear TCD2252. Compared with the traditional linear calibration method, the precision was improved by the use of characteristic spectrum of helium lamp and second-order calibration method. The test data was published to internet real-time, therefore the remote users can browsing the spectrum measurement easily. The application program was designed with LabVIEW8.5 to achieve the functions of data acquisition, processing, analysis, display and web transmission. The result indicated that measurement error is within acceptable range.
