In this paper, we present a simple Stokes parameter measurement method for rotating quarter-wave plate polarimeter. This is used to construct model describe the principle of how magnitudes errors influence deviation output light parameter, on basis accuracy analysis retardance error plate, misalignment analyzing polarizer, and phase shift measured signals, which will help us determine these then acquire correct results parameters. The validated by experiments left-handed circularly polarized...

The climate on Earth is affected by the Sun. It thus necessary to determine solar spectral irradiance (SSI) with high precision ground for improved accuracy of models used Earth. To achieve this purpose, a monitor (VISM) wavelength ranging from 380 2400 nm developed. In work, optical design and calibration VISM are explored, two paths designed SSI in wide region. One them main path through which sunlight dispersed imaged single Féry prism. A laser concave mirror other rotated angle prism,...
A hyperspectral irradiance monitor (HIM) is designed to measure the direct solar spectral on ground, which can be used for research climate change and vicarious calibration. The spectrometer uses a Féry prism disperse converge light, linear image sensor (NMOS) measures ranging from 400 nm 1100 nm. instrument utilizes two flat mirrors fold optical path, software optimize key parameters. dispersion equation of characteristic wavelengths laser are utilized calibration, uncertainty calibration...
The surface reflectance is one of the most critical parameters during a field vicarious calibration. Traditional methods to measure require personnel at test site. A ground-viewing radiometer built automatically. has eight channels in wavelength range from 400 nm 1550 nm. optical system temperature controlled. feedback resistor calculation method introduced that used obtain reasonable signal. Solar radiation-based calibration and two other laboratory are absolute coefficients radiometer....
