Patent ID: 10495516

Abstract:
The invention relates to a multi-channel spectrometer device (10) for detecting/quantifying a predetermined analyte (5) in a medium (6). The device (10) comprises an input (11) for receiving radiation (7), a first plurality of optical modulators (12) adapted for transforming the radiation (7) in accordance with a first transfer function, and a second plurality of optical modulators (13) adapted for transforming the radiation (7) in accordance with a second transfer function. The spectrometer device also comprises a detector (15) for generating output signals (4) indicative for the intensity of each transformed radiation signal. The ratio of the number of optical modulators in the first plurality and the number of optical modulators in the second plurality is determined by the ratio of a reference spectrum of the predetermined analyte transformed by the first transfer function and the reference spectrum transformed by the second transfer function.
