From: Partial recovery of visual function in a blind patient after optogenetic therapy
a. GS030-MD consists of two units connected by a high-speed link. The head unit (left) hosts the camera which acquires the natural scene in a stream of asynchronous address-events representing pixel coordinates of local relative light intensity changes. The processing unit (right) encodes the visual stream in real time and creates binary images that are sent to the projector in the head unit. The projector, which is also mounted on the head unit (top), is placed in front of the eye. b. Front and rear view of the head unit. The camera is placed at the center facing the outside world. The projector is placed in front of the treated eye, facing the eye, and can be moved horizontally so as to be placed precisely in front of the treated eye’s pupil, since inter-pupillary distance varies between patients.
