Distinguishing Technology of Optical Maser Wavelength based on the ARM9 Embedded Platform

In this paper, the fast distinguishing technology of optical maser wavelength is researched in theoretically and practically in detail using principle of optical rotation effect. Using Wollaston prism as polarization analyzer efficiency, two light path detecting method avoids errors which induced by fluctuate of source. This method can improve the measurement precision. The hardware platform chooses the ARM9 embedded platform based on the S3C2440 with fast operation and strong extended function. The software platform uses the embedded Linux OS. The measurement data show that hardware platform and software platform reaches the expectation effect and improves the precision, and verifies the validity and the practicality.
