二维光学神经网络自由空间互连结构设计

ARCHITECTURE DESIGN OF AN OPTICAL NEURAL NETWORK WITH LENSLET ARRAY

本文分析了以透镜阵列元件建立空间互连通道的光学神经网络中神经元数的理论极限．为了提高网络中的神经元数，我们提出了一种并行结构设计，该结构克服了小透镜成象中的离轴象散的影响，提高了系统的光能利用效率，同时降低了系统中的对位精度误差，提高了互连运算精度。

A theoretical limitation on the neuron numbers(N×N)of a spatial interconnection systembased on lenslet array is analysed in this paper. In order to improve the limitation,we proposed aparallel interconnection architecture. For alleviating the off-axial aberration and achieving high lightefficiency,the limitation is improved evidently.A detailed analysis is described in the paper.
