Low-loss silica glass image fibers suitable for long-distance image transmission have recently been developed and expected to become a powerful tool for monitoring the object existing under specific circumstances, such as high pressure, high temperature and heavy radiation fields". An image fiber has a closed-packed structure consisting of a large number of elementary fibers which typically have a core of several microns and a cladding of ten or more microns in diameter. An object image is transmitted independently through each elementary fiber. Therefore, the incoherent light from a thermal source is used in usual cases for illumination. However, if the laser light that is coherent in a temporal sense is used instead of the incoherent thermal light, the laser speckles appear over the transmitted image due to random interference between waves emerging from different elementary fibers. In this report, the dynamic statistical properties of image-plane speckles produced through an image fiber by a moving non-stationary object are investigated.
