Abstract
Abstract An apparatus for interfacing holographic and electronic data comprises an input/output port for the interfacing of a holographic wavefront interference pattern and an electronic array capable of producing digital electronic information from a holographic wavefront input and for converting electronic information into holographic information using optical fibers, sensors, and optical switches. In one embodiment a plurality of optical fibers having a small end and a large tapered end are operably combined with a plurality of optical sensors wherein each of said optical sensors provide a digital signal of 1 if lit and a digital signal of 0 if unlit.
