Abstract :
In modern manufacture, the need of precise dimension measurement with no touch is bigger and bigger. This paper studies and designs a precise photoelectric measurement device for dimension integrated with optics and signal proceeding technology. Using narrow-spectrum of high brightness LED as lamp-house, even parallel light comes into being when passing special optical structure. Adopting high resolution linear CCD sensor and subdivision technology and integrated with digital signal proceeding technology, the system has achieved steady micron-grade dimension measure. We select TMS320-F240 DSP as microprocessor, and use touch screen with big screen to display graph. The device is convenient and exact to use, and its application foreground is very good in various fields such as precision machining to the manufacture.
