| 摘要 |
Echelle gratings and microelectromechanical system (MEMS) digital micromirror device (DMD) detectors are used to provide rapid, small, and highly sensitive spectrometers. The new spectrometers are particularly useful for laser induced breakdown and Raman spectroscopy, but could generally be used with any form of emission spectroscopy. The new spectrometers have particular applicability in the detection of improvised explosive devices.
