A miniature spectroradiometer for dosimetry
SPIE Proceedings, 1989A miniature spectroradiometer for dosimetry is proposed. The design goal is a small and easily portable device which is intended to be used with and operated by a personal computer or a single-board computer. It has several applications. It may be used as a general purpose spectroradiometer in the ultraviolet, visible, and near infrared spectral ...

A LABORATORY INVESTIGATION OF TWO ULTRAVIOLET SPECTRORADIOMETERS
Photochemistry and Photobiology, 1994Abstract—Spectral measurements of the solar UV irradiance at the earth's surface depend critically on the characteristics of the spectroradiometers and the procedures used in their calibration. Two UV spectroradiometers were subjected to a series of laboratory tests to investigate which factors were most significant in limiting the reliability of the ...

High-speed spectroradiometer for remote sensing
Applied Optics, 1987A high-speed spectroradiometer designed for spectral reflectance measurement in remote sensing is described. This instrument uses a monochromatic grating and a photomultiplier system for light detection and sweeps over the 400-850-nm wavelength spectral range with the spectral resolution of 2 nm within 1 s.

Staring infrared imaging spectroradiometer
SPIE Proceedings, 1995A design approach for developing a staring-dispersive infrared imaging spectroradiometer utilizing a fiber-optic image formatter to simultaneously capture, at rates greater then 100 Hz, 256 high-resolution spectral images of a 2D scene is described. Detailed performance analyses confirm that the spectral radiance within the image scene can be measured ...

European intercomparison of ultraviolet spectroradiometers
Environmental Technology, 1993Abstract Accurate spectral measurements of solar ultraviolet radiation are essential to an understanding of the photochemical and biological effects of ozone depletion. The analysis of spatial and temporal variations in ultraviolet fluxes will depend on the collation of spectra from many independent laboratories.

Spectroradiometer Calibration Methods and Techniques
1997As virtually all the environmental effects of ultraviolet radiation are strongly dependent on its wavelength, it is essential to obtain reliable measurements of the solar spectral irradiance received at the surface of the Earth. Such measurements, gathered at different times and places, can only be related to each other, and applied to the calculation ...

A Time-Integrating Multichannel Spectroradiometer
Applied Optics, 1965A time-integrating multichannel spectroradiometer has been designed and constructed primarily to provide an accurate means for measuring the relative spectral energy output of flash lamps. The energy from the flash lamp is collected in an integrating sphere and is presented to an array of narrow-band, interference-type filters covering the region from ...

The wavelength calibration of a monochromator based differential spectral responsivity (DSR)-facility becomes of crucial importance if the spectral responsivities (SR) of solar cells under test differ significantly from the SR of the reference detector. Since the latter is mainly based on crystalline silicon, this problem is of major importance for the
