Spectroradiometry and Radiometric Calibration

light measurement for spectroradiometry and radiometric calibrationSpectroradiometry, the measurement of absolute optical radiation at each wavelength, is applicable to a variety of settings, including measuring the spectral energy output of a lamp, LED display, or other light source to determination of the flux of sunlight reaching a forest floor or other scene. Unlike other science research fields where it is possible to collect a sample and transport it to an instrument for measurement, characterizing spectral flux requires bringing the instrument to the measurement site for in-situ analysis. Specific applications include the calibration of solar simulator systems and other test sources for solar energy research, pre and post-launch radiometric calibrations of satellite imaging sensors, plant growth chamber calibration, as well as surface measurements of a wide range of other spectral radiance and irradiance values.

FieldSpec spectroradiometer specifically for performing these types of measurements.

ASD spectroradiometers are calibrated using a NIST-traceable, 1000W quartz-halogen lamp and a highly regulated power supply, producing a known irradiance, on a standardized Spectralon® diffuse reflectance panel. The data are downloaded into a calibration file that is accessible when the instrument is placed into the radiance mode and a spectrum is measured.
