摘要
An optical memory (100) in which data is stored in an optical data layer (190) capable of selectively altering light such as by changeable transmissivity. Data is organized into a plurality of regions or patches (called pages) in which each page contains a field of data spots storing binary data as the presence or absence of a hole. The data is illuminated by controllable light sources (150) and an array of single element diffractive imaging lenslets (210), one for each data page, projects the image onto a common array of light sensors (270).
