We have newly developed a high definition FOP with a single fiber pitch of 3 μm and a tapered FOP which has the capability of magnifying or minifying the transmitted image. These FOPs provide many advantages including high resolution. high transmission efficiency, small envelope size, large useful area and low image noise. These improvements allow to expand the applications with the CCD and the linear image sensor. This report discusses these features as comparing with lens and standard 6 μm FOP.
