Paper Abstract

An optical fiber holographic endoscope (OFHES) has been developed, in which the reference beam, illuminating object beam, and the image of the object are transmitted by a single-mode fiber, a multimode fiber bundle, and a multimode fiber image bundle (MFIB) respectively. The resolution of OFHES is 30 lin/mm higher, field depth 30 mm more, and measuring range 30 X 30(mm)2 larger. Based on understanding the image transmitted characteristic of MFIB, we describe the effect of the multimodes and crosstalk in MFIB on the hologram recorded in the system by the OFHES.
