Paper Abstract

We present an image quality improvement using the speckle method in an in-line digital holography by means of a multi-mode fiber. In the proposed method, we use the speckle field emitted from the multi-mode fiber as both the reference wave and the wavefront illuminating the object. To capture multiple holograms, the speckle fields are changed by vibrating the multi-mode fiber using a vibrator. This method has an advantage in that the alignment of an optical setup becomes ease due to the introduction of an optical fiber and the speckle method can be readily performed by means of a vibrator.
