Design of photo-electric diameter-measuring device based on FPGA
2011
A non-contact optical-electric measuring principle is introduced that is based on pulsed laser light source and high-precision CCD imaging technology. The diameter- measuring device design framework and some basic structure units are given. Meanwhile, the FPGA (Field Programmable Gate Array)-based devices of the linear array CCD data acquisition and signal-processing system including various functional modules are discussed emphatically.
