SR 5000N: a new IR spectroradiometer implementation

摘要

In a previous paper we have presented the design and the expected performance of the latest generation of visible/infrared spectroradiometric system for field use, called SR 5000N. Examples of significantly advanced performance are expected in compactness, field of view response uniformity, measurement speed, ease of pointing the Line of Sight (LOS) on the object to be measured, and interchangeability of configuration modules, such as fields of view size, wavelength range and detectors. One unique and advanced feature of this system is that a Visible/Near IR spectrometer is incorporated in the system to provide, together with the IR optical channel, a simultaneous measurement of the same object in the whole 0.2 to 14.5 microns spectral range. In this paper we present the actual system after being built and some performance results on field of view uniformity and symmetry. Unfortunately, due to delays in R&D schedule, not all features have been completed so far and therefore not all results can be shown here as we initially planned. Additional performance results will be reported in a future paper, as soon as the system development and characterization will be completed.
