We present experimental results from an all-optical associative memory that combines holography and phase conjugation. The device has the capability to recall a complete image when merely a portion of the stored image is input to the system. Multiple superimposed two-dimensional images with gray scale can be stored and recalled. In addition, we have demonstrated the system's invariance to translation of the input images.
