Remote Optical Sensing
Abstract
One of the major advantages of optical systems is their ability to process a great deal of information in parallel. The optical system discussed here transmits a complete image through a single optical fiber. This transmission system preserves the three-dimensional and color information of the image. The resolution is limited by the number of modes that can propagate in the fiber. The image is inserted and retrieved from the fiber by tapered input and output sections connected to the ends of the fiber. We built and tested a prototype image transmission system. We successfully transmitted a standard AF target through the system. We here present an analysis of how an image propagates through such a system. The model is derived from the electro-magnetic field equations. The image transmitted through the fiber does not necessarily have to be a picture of a real physical object. It could consist of various bits of information transmitted through the fiber in parallel. The transverse electric as well as the magnetic field modes propagate in the structure at different speeds. However, at periodic intervals all modes are in phase.
