Abstract
A multi-channel detector assembly for downhole spectroscopy has a reference detector unit optically coupled to a reference channel of a source and has a measurement detector unit optically coupled to a measurement channel of the source. The reference and measurement detectors detect spectral signals across a spectral range of wavelengths from the reference and measurement channels. Conversion circuitry converts the detected spectral signals into reference signals and measurement signals, and control circuitry processes the reference and measurements signals based on a form of encoding used by the source. Then, the control circuitry can control the output of spectral signals from the source based on the processed signals or scale the measurement signal to correct for source fluctuations or changes in environmental conditions.
