A field spectral radiometer has been granted a patent (Publication Number: US11885671B2) for its innovative design and functionality. The radiometer includes a support structure with a remote sensing head that has a central axis defining the viewing direction, along with first and second optical elements on either side of the axis for different wavelength ranges. An instrumentation assembly on the support structure includes detection paths associated with the optical channels, with specific components like diffraction-based spectrometers and semiconductor alloy-based detectors for accurate measurements.

Furthermore, the radiometer's design allows for a dynamic range greater than 1.5×105, ensuring precise and reliable data collection. The calibration process involves manipulating the field of view of the radiometer to measure solar radiance, atmospheric transmission, and surface reflectance. By reflecting solar light towards the system via a reflector array and adjusting the image signal based on these measurements, the radiometer provides calibrated data for accurate analysis. Additionally, the calibration of the radiometer involves rotating the deployment arm to position the remote sensing head in alignment with a calibration light source, ensuring consistent and accurate calibration for reliable results.
