solar energy conversion/ reflectanceabsorptancemulti-plate planar windowray-tracing techniquetransmissionA ray-tracing technique is used here in order to compute the overall transmission, reflection and absorption of composite layers. Formulae for these optical properties and their components of transparent ...
摘要: This study considered the premise that subcellular particles in leaves contribute to the reflectance (R) and absorptance (A) of near-infrared (IR) (light 750 to 350 nm).关键词: plant physiology, plant biochemistry, horticultural crops ...

An integrating-sphere system has been designed and constructed for multiple optical properties measurement in the IR spectral range. In particular, for specular samples, the absolute transmittance and reflectance can be measured directly with high accuracy and the absorptance can be obtained from these ...
to transmit radiation, equal to the ratio of the transmitted flux to the incident flux; the reciprocal of the opacity. For a plate of material the ratio of the flux leaving the entry surface to that reaching the exit surface is the internal transmittance. Symbol:τComparereflectance,absorptance...
It is also evident that in the thermal radiation region (around 10 μm) both reflectance and transmittance of plain glass remain low, and by Kirchhoff’s law (i.e., α + ρ + τ = 1, ε = α in thermal equilibrium) the absorptance (and consequently the emittance) of glass is ...
