Abstract

We demonstrate coherent image transmission through a single step-index multimode optical fiber and its backpropagation by using delayed phase conjugate waves through the same fiber and we propose an optical fiberscope as a possible technical application. As for the image transmission in this kind of optical fiber, it is examined numerically and the effects of several parameters are shown. The effect of multiple exposure for speckle reduction is also demonstrated as well as the possibility of reconstruction of any desired cross section of a 3-D optical field of the object.
