[3D1-2] Speckle Reduction in Electro-Holography by Vibrating Multimode Optical Fiber
Electro-holography, Speckle reduction, Vibrate multimode fiber
In electro-holography which the reconstruction light is supplied by a multimode optical fiber, the coherence of the reconstruction light is adjusted by vibrating the optical fiber with an actuator controlled by an electric signal, and the quality of the reconstructed image is controlled.
