| 摘要 |
The subject invention relates to a method of mitigating the effects of spurious background signals in spectroscopic measurement systems. The design of a broadband imagining spectrometer is disclosed that enables direct measurement of the spurious optical background intensity during spectroscopic measurements of a sample. The background is measured on a two dimensional surface coincident with the spectrometer exit plane. The background contribution is used to correct the measurements improving the accuracy of the spectroscopic intensity measurement.
