High Speed Noncontact Displacement Measuring System using FPGA

摘要：

　　According to optical triangle theory,by detecting the position of reflection light spot on line array CCD.The pels signal is transformed into data flow by a high speed ADC for processing with the circuit composed of FPGA.The system can calculate the relative displacement between the reference point and the objects detected.The system has 50MHz sampling rate and USB2.0 bus,so it also can be applied in other information acquisition fields.

关键词： displacement measuring optical triangle line array CCD FPGA USB2.0
