Spectrometer with dual digitizer for high-dynamic range spectroscopic data collection

摘要

A spectrometer (110) having an interferometer, a detector (120) that produces a detector signal (20), and a dual-digitizer system including two analog-to-digital converters that simultaneously digitize low-gain and high-gain versions of the detector signal, and suitable data structures and associated firmware for merging the two resulting sets of digitized data into a single, high dynamic range set of data.
