A wide-range fiber spectral instrument covering in 400∼2500nm

摘要

To meet the requirements of outdoor field mineral analysis and remote sensing ground verification spectral analysis, the wide-range fiber spectral instrument covering 400nm–2500nm is developed. This article illustrates the design of the optical, mechanical and electrical parts of the instrument. The optical has a small size, a high spectrum resolution and the quality of signal and the velocity measuring has reached what we need. The final results demonstrate that while implementing the measurement of wide spectrum, the instrument is improved in size, spectrum resolving power, signal quality and measuring speed. Ideal spectrum data are acquired.
