We describe the design and development of an adaptive spectrometer that actively manages dynamic range mismatch between source signals and the spectrometer’s detector. The introduction of an inexpensive digital micromirror array yields performance improvements compared to a traditional device. Simulation results are presented that indicate real-world scenarios in which the adaptive spectrometer will yield superior performance. Experimental results from a first-generation prototype adaptive spectrometer confirm the expectations of the simulations.
