测量固体线膨胀系数是工程设计中的一项重要工作。这套非接触固体线膨胀系数测量系统利用激光三角法进行了设计。通过采用线阵CCD作为信号传感器来实现自动化测量。通过采用无衍射贝塞尔光束来提高测量精度和增大测量范围。
Measuring solid linear expansion coefficient is an important project in engineering design. The non-contact solid linear expansion coefficient measurement system was designed using the laser triangulation method. Through the use of linear CCD as a signal sensor to achieve automated measurements. By using a non-diffraction Bessel beam to improve measurement accuracy and increase the measurement range.
