A Versatile Spectroradiometer and Its Applications

Applied Optics, 1967
A spectroradiometer is described which is designed to make measurements of spectral radiance, irradiance, transmittance, and reflectance. In one minute the Hilger D300 monochromator is set to the next wavelength to be measured and a measurement is made of (a) the dark current of the photomultiplier, (b) the photocurrent produced by the reference source,

Realization of an infrared spectroradiometer

Applied Optics, 1991
This paper describes a fully automatic spectroradiometer designed to measure the absolute spectral irradiance of light sources in the 800-2400-nm spectral range by direct comparison of radiation sources with a standard source, both placed the same distance away. The total estimated uncertainty in the comparison process is

Development of a broadband spectroradiometer

2008 33rd IEEE Photovolatic Specialists Conference, 2008
Spectral measurements of the solar radiation at the Earth's surface are important for meteorological, environmental, photovoltaic, and biomass study etc. Especially a long-term measurements and in-situ measurements are valid and efficient methods. Two types of spectroradiometers were developed for making those measurements in all weather conditions ...

An Airborne Spectroradiometer*

Journal of the Optical Society of America, 1960
A system is described for acquiring spectroradiometric data concerning objects in space from an airborne platform. The system operates in the 0.25 to 15-μ spectral region; large collecting optics, precise optical tracking, and background discrimination in the entrance optics permit the acquisition of high resolution and sensitivity.

A Spectroradiometer for Field Use

Review of Scientific Instruments, 1973
The configurations and operation of a field spectroradiometer (Exotech model 20-B spectroradiometer) that measures the intensity of incident and reflected radiation from 0.37 to 2.52 μ and emitted radiation from 2.76 to 13.88 μ are described. The instrument was built by Exotech Inc. from specifications and plans developed by the USDA.
