A high resolution, field portable spectrometer

The design of a high resolution, field portable spectrometer system is presented. The system provides the spectral resolution previously available only with laboratory based systems. The system's portability allows for essential in situ measurements, provides rapid acquisition and calibration of spectral reflectance data over a wavelength band from about 300 to 1000 nm. Features include a calibration scheme for normalizing data to the incident radiation, and the injection of a spectral calibration signal. Laboratory tests indicate that the system will perform as expected, and plans are being made to integrate the system with a ground based active and passive microwave data acquisition system.
