METHOD AND SYSTEM FOR MEASURING OPTICAL PROPERTIES OF A MEDIUM USING DIGITAL COMMUNICATION PROCESSING TECHNIQUES

摘要

A system (20) for measuring properties of a medium (30) includes an electromagnetic generator (26) for forming a CW carrier, a digital encoder (24) for forming a digital message, and a modulator (28) for modulating the CW carrier with the digital message to form a digitally modulated CW carrier. The medium (30) provides a channel for propagating the digitally modulated CW carrier. The system further includes a receiver (32) configured to receive the propagated, digitally modulated CW carrier, and a processor (56) for measuring at least one property of the medium. The medium (30) may be disposed within a gaseous atmosphere, a body of water, or a cell of a laboratory.
