Patent ID: 8735803

Claim:
A detector assembly for downhole spectroscopy used in conjunction with one or more light emitters of a source assembly, the detector assembly comprising: a reference unit having at least one reference detector and detecting first spectral signals across a spectral range of wavelengths from a reference channel of the one or more light emitters; a measurement unit having at least one measurement detector and detecting second spectral signals across the spectral range of wavelengths from a measurement channel of the one or more light emitters after interaction with a fluid sample; conversion circuitry communicatively coupled to the reference and measurement units and converting the first and second spectral signals into reference signals and measurement signals; and control circuitry communicatively coupled to the conversion circuitry and to the one or more light emitters of the spectral signals, the control circuitry processing the reference and measurements signals and configuring output of the spectral signals from the one or more light emitters based at least on the processed reference signals, wherein to configure the output, the control circuitry at least controls the one or more light emitters to configure light emitter intensity.
