The Determination of Precise Coordinates for Bohyunsan Optical Astronomy Observatory by GPS [PDF]
Journal of Astronomy and Space Sciences, 1995 We determined three dimensional precise WGS 84 coordinates if two points in Bohyunsan Optical Astronomy using the GPS. One if the two points is the center on the top of pier for 1.8m telescope, and the other one is placed on the hill beside the dome of 1.

Near‐Infrared Polarimetric Imaging With Nonlinear Flat‐Optics
Laser &Photonics Reviews, EarlyView.ABSTRACT A compact and broadband polarimetric imaging platform is presented, based on second‐harmonic generation (SHG) in nonlinear flat‐optics. The system employs periodic all‐dielectric AlGaAs gratings to induce polarization‐dependent SH emission, enabling pixel by pixel direct retrieval of the full Stokes vector from an input intensity distribution ...

Anisotropic Diffuse Radiation Model of Photovoltaic Systems
Progress in Photovoltaics: Research and Applications, EarlyView.Monthly incident diffuse energy—isotropic and anisotropic models. ABSTRACT The diffuse solar radiation is a component of the global solar radiation and may contribute a significant percentage (50% and above in some locations) of the electric output energy of Photovoltaic (PV) systems.
