Speckle mechanism in holographic optical imaging.
Speckle imaging was investigated by using dynamic holography and photorefractive AlGaAs/GaAs multiple quantum wells in a holographic optical imaging system. We showed that the speckle contrast depends on holographic fringes and the photorefractive effect. We further demonstrated that a moving grating technique can be used to suppress the random speckle.
