Spectrum Measurement via Low Cost Spectrum Sensor On-a-Chip

摘要：

Fine spectrum measurement with the application of non-negative least-square (NNLS) algorithm to low-cost filter-based Spectrum Sensor is demonstrated. Compare to conventional Moore Penrose pseudo-inverse technique, NNLS is found particularly effective for noise reduction in reconstruction of narrow-band spectra. Low cost spectrometer with an on-a-chip scale can be therefore anticipated.
