MONTEJO VALDES, Pablo et al. Reconfigurable hardware for reconstruction of transmitted videos using Incoherent Optical Fiber Bundles. EAC [online]. 2013, vol.34, n.1, pp. 59-69. ISSN 1815-5928.

Image transmission using incoherent optical fiber bundles (IOFB) requires calibration information used for reordering the fiber positions and reconstructing the original image. Another important demand consists in enough memory to store image during reconstruction and during retransmission. Most of the time, these aspects require to use external memory when FPGAs are used. This paper presents a solution in order of resolve this problem. A system on chip is proposed capable of to store needed information and images using a low cost FPGA. Two solutions are presented, the best is implemented. Results are showed. The use of this method makes possible to transmit video using IOFB and reconstruct originals images almost in real time because of its low latency. This proposal could be used in autonomous systems taking advantage of its compaction level, reliability and low costs.
