Noncontact measurement technology for vibration detection of distant object

According to the characteristics of the vibration object and the demand of measurement, the linear CCD detection technology was applied to realize the noncontact, distant and automatic measurement of vibration magnitude. The system completes the data transmission between CCD module and USB port by the hardware designation and realizes the vibration detection of the object via determining the center offset of the fixed bar code. The user application programs were developed by taking Visual C++6.0 as the development environment. The technology has the advantages of high precision, easy operation, high quality and low cost. Its good performance in field measurement was also verified.
