Free space image communication system and method
First Claim
1. A system for communicating a data set through free space, the system comprising,a encoding means for encoding the data set into an pixelized image,a display means for converting the pixelized image into a displayed image and projecting the displayed image through free space,a camera means for receiving the display image and converting the displayed image into the pixelized image, anda decoding means for decoding the pixelized image into a data set.

Abstract
A communication system including a transmitter and receiver, encodes a data set into a pixelized image for display and projection transmission through free space to a receiving camera regenerating the pixelized image which is then decoded back into the data set, the image transmission increases data transmission rates over serial bit free space communication by coding an entire data set into one pixelized image matched to one of several image patterns to which the data set may be coded using various image coding schemes, as examples, hexadecimal, angular and symbolic image coding schemes are particularly disclosed.

10. A method of communicating a data set through free space, the method comprising the steps of
encoding the data set into a pixelized image, converting the pixelized image into a display image, projecting the display image through free space, receiving the display image, focusing the display image, photodetecting the display image, converting the display image into the pixelized image, and decoding pixelized image into the data set.
