Description
Summary:碩士 === 龍華科技大學 === 電子系碩士班 === 94 === The purpose of the study was to design a measurement and data acquisition system for Quadrant Detectors (QD). This designed system include two parts—analog processing circuit module and high speed data acquisition card. The analog processing circuit module was developed to reduce circuit noises and to acquire signals of quadrant detector. The other high speed data acquisition card adopted a USB 2.0 chipset as the transmission interface to PC and the data acquisition applied the Complex Programmable Logic device (CPLD) component to simplify the related peripheral circuits. In addition, the CPLD was to provide 8 A/D channels and acquires 4 set of sensor signals at one time. The result of the experiment reveals that the residual error of the system was within ±1μm, and its resulation was 0.3μm. The designed USB measurment and analog systems not only meet the requirements of high precision optical position, but also equipped with the integrated capability to other related systems.
