ScholarBank@NUS Repository. https://doi.org/10.1117/12.974939 | Abstract: | A novel phase generated carrier (PGC) demodulation algorithm based on differential-cross-multiplying (DCM) and arctangent function (ATAN) is proposed in this paper. We investigate the stability with light intensity disturbance (LID) and the harmonic distortion due to nonlinearity both theoretically and experimentally. The nonlinearity of the proposed PGC demodulation algorithm has been analyzed. Compared with the traditional PGC-arctan and PGC-DCM algorithm, this PGC algorithm inherently has much lower total harmonic distortion (THD) as well as high stability with LID. © 2012 SPIE. | Source Title: | Proceedings of SPIE - The International Society for Optical Engineering | URI: | http://scholarbank.nus.edu.sg/handle/10635/110921 | ISBN: | 9780819491039 | ISSN: | 0277786X | DOI: | 10.1117/12.974939 |
