1P284 High-precision frequency-domain fluorescence anisotropy measurement using a waveguide LN modulator for dye rotational motion analysis(26. Measurements,Poster,The 52nd Annual Meeting of the Biophysical Society of Japan(BSJ2014))
Frequency meter measured frequency of analog periodic signal in its frequency domain and used the software control program to replace the complex outside counting circuit. ARM7 development board, LPC2103 chip, and AD9833 chip made up of a complete system. This paper gave the designing schemes of hardware and software system and analyzed experiment results, which prove that this design reaches expectant target with less hardware and simpler structure.
