We describe a shift-invariant all-optical holographic associative memory implemented using phase conjugate mirrors and Fourier transform holograms. A key feature of our system is the large storage capacity obtained through the use of nonlinearities in the correlation domain. The use of angularly multiplexed plane wave reference beams allows access to the correlation domain where nonlinearities in the phase conjugate mirrors can be used to reduce greatly crosstalk and correlation noise.
我们描述了一种使用相位共轭镜和傅里叶变换全息图实现的平移不变全光全息关联存储器。我们系统的一个关键特性是通过在关联域中利用非线性获得的大容量存储。使用角度复用平面波参考光束可访问关联域,在该关联域中,相位共轭镜中的非线性可用于大幅降低串扰和关联噪声。
