在时间平均电子散斑干涉仪中，利用连续波（cw）照明测量振动物体的相位和振幅，证明了激光二极管发射波长的调制是一种外差技术。用单模光纤干涉仪对该技术进行了验证。
Modulation of the emission wavelength of a laser diode is demonstrated as a heterodyning technique for measuring the phase and amplitude of a vibrating object using continuous wave (cw) illumination in a time-averaged electronic speckle pattern interferometer. The technique is demonstrated with an interferometer constructed from single mode optical fibre.
