Description

technical field [0001] The invention relates to a system in the technical field of biomedical engineering, in particular to an artificial vision simulation and experiment system. Background technique [0002] Many researchers are currently investigating the use of visual prostheses to assist in partial restoration of visual function. Different vision prostheses are available for vision loss due to different diseases of the visual system. For the damage of cells inside the retina, the loss of eyeballs, the loss of vision caused by optic nerve diseases, etc., the visual cortex can be stimulated to achieve the purpose of restoring vision. In addition, under the current limited medical conditions and technical level, the development of senses (tactile, auditory) Alternative electronic aids are also becoming a hot topic. [0003] Whether stimulating the retina, optic nerve or visual cortex, in the realization of artificial visual prosthesis, a key technical issue is the transmi...
