| Abstract: | Based on the optoelectronic transformation technology and the parallel-laser-scanning inspection principle, a transmission laser scanning inspection system for diameter measurement was designed. A parallel-flat-crystal was used to make up the transmission laser scanning transmitter so that highly paralleled scanning beam can be acquired in the absence of scanning objective lens. The front data processing module and the communication module were included in the measurement and control platform based on FPGA.... |
