Fig. 1 Neural array imaging system and its principle behind its ability to break the trade-off between aperture size, ffeld of view, and imaging quality. (a) The system consists of a metalens array, a CMOS sensor and a computing layer chip. Metalens array modulates the light from the target scene, which is captured by the CMOS sensor and used as input to the reconstruction algorithm for real-time scene reconstruction. (b) Schematic diagram of the neural array imaging model and the traditional point-to-point imaging model. (c)-(d) and (f)-(g) compare the wavefront aberrations and the modulation transfer function (MTF) distribution of the traditional point-to-point imaging model and the neural array imaging model in large-aperture cameras. The black dashed lines represent a reference lower bound for the recoverable MTF constrained by the system noise level. (e) and (h) compare the performance map of the two imaging models across various metrics.
