A system for calibrating a plurality of user sensors includes a calibration management system comprising a processor and a node services module and a plurality of calibration nodes disposed at a plurality of geographical locations. The processor is communicably coupled to the plurality of user sensors, the node services module, and the plurality of calibration nodes and operable to: provide calibration node information to a system associated with one of the plurality of user sensors and cause the calibration node to perform at least one calibration action after providing the calibration information, the calibration action may include performing an environmental measurement and/or providing a calibration reference signal to the user sensor. The processor is also operable to provide calibration results information containing results of the calibration action to the system associated with the one of the plurality of user sensors.

Calibration network systems and methods of using the same

A field spectral radiometer includes a support structure and a remote sensing head disposed on the support structure. The remote sensing head includes a central axis, a first optical element disposed on a first side of the central axis and defining a first optical path for a first optical channel, and a second optical element disposed on a second side of the central axis and defining second optical path for a second optical channel. An instrumentation assembly disposed on the support structure. the instrumentation assembly includes a first detection path associated with the first optical channel and a second detection path associated with the second optical channel, the first and second detection path include optical indexers for manipulating the first and second optical channels. The field spectral radiometer may include a calibration assembly disposed on the base. The calibration assembly may include a calibrating light source for calibrating the remote sensing head.

Field spectral radiometers including calibration assemblies

A reflector array includes a base, a rotating support pivotally coupled to the base, and an array actuator comprising a rotating element coupled to the rotating support. The reflector array also includes a plurality of reflectors attached to the rotating support such that the plurality of reflectors rotate in unison in conjunction with one another relative to the base as the array actuator rotates the rotating element. First and second reflectors are coupled to the rotating support via separate reflector support elements that are rotatable to adjust elevation angles of the first and second reflectors.

Protected reflector array for a calibration system

An illumination system includes an illumination source configured to emit illumination light and a dispersive optical element configured to generate an angularly dispersed optical signal from the illumination light that is used to generate a spectral image. A digital micro-mirror device (DMD) includes an array of reflective elements that receive the spectral image and direct a portion of the spectral image to an integrating sphere. A controller is configured to calculate a subset of an array of reflective elements of the DMD to activate based on a target illumination output signal using a calibration model of the illumination system. The controller is also configured to activate the subset of the array of reflective elements to change the portion of the spectral image directed to the integrating sphere to generate an illumination output signal that substantially matches the target illumination output signal.
