This paper mainly studies the laser interferometer by PC control means, to adjust optical measurement control device, make up for the traditional laser interferometer manually adjust the shortcomings of low precision, difficult to quantitative control. This system by a Windows forms application control commands sent, by PL2303HXD level conversion module to CC2530 MCU, MCU control action accordingly according to the command to complete. By optical measurement adjustment device with high precision motor mechanical parts combination, can adjust the measurement parameters, to meet the requirements of the environment and the measurement accuracy of a laser interferometer. It has the characteristics of quantitative control, convenient operation, reduces the artificial adjusting the air flow and vibration influence on measuring, make sample detection more accurate and efficient.
