ABSTRACT:
A method of decoding spectral data that has been encoding by modulation of a spectrum of light to produce data bits from a source using on/off and off/on transitions to represent each data bit. A start data bit with a constant width precedes each segment of light representing the data bits. The intersection of the output of spectral detectors and a hysteresis curve determines a transition through which information is obtained from the encoded data.
