Fig. 4: Fully integarted form of the curved neuromorphic imaging device.

a Photograph of an integrated imaging system that consists of a plano-convex lens, cNISA, and a housing. The inset shows the components before assembly. b Exploded illustration of the curved neuromorphic imaging device. c Photograph of cNISA on a concave substrate. d Schematic diagram of the customized data acquisition system for measuring the photocurrents of individual pixels in cNISA. e–h Demonstrations for deriving a pre-processed image from massive noisy optical inputs (e.g., acquisition of a pre-processed C-shape image (i), decay of the memorized C-shape image (ii), erasure of the afterimage (iii), and acquisition of a pre-processed N-shape image (iv)). Figure 4e shows applied optical inputs and an applied electrical input. Figure 4f shows obtained images at each time point. Figure 4g and h show the photocurrent obtained from the pointed pixels at each time point.
