The experimental results show that the method can overcome the limitations of the critical angle between the object and reference beams, and omit the frequencyaliasing.
实验结果表明,该方法可有效地突破最大物参角的限制,同时可以消除由于欠采样造成的频谱混叠现象。

Author suggests that increasing number of measurement taps and prolonging sampling time and enhancing sampling frequency will decrease signals aliasing and leakiness.
For bandpass signal under digital quadrature sampling, there is spectrum shifting. Although the sampling frequency satisfies the sampling theorem, it may cause spectrum aliasing.
