The function of illumination optics for projection displays is to direct light source onto a small area of microdisplay within a limited incident solid angle , and therefore the collection efficiency is especially important compared to other illumination applications , which is also the main technical issue for led application to projection displays
摘要投影显示之照明系统须将光能量集中照明于一小面积与小角度之内，相较于其他照明之应用，其集光效率之考量更为严苛，亦为发光二极体于投影显示照明应用中最主要之技术课题。
To the influence of the plateau terrain , the impact of the elevation and the roughness of terrain to every energy component out and incoming are study , and basing the soil spectrum model proposed above , a new radiative transfer model of terrain area was put forwarded in which the soil water content , lai , terrain roughness and elevation were considered synchronously , and incoming scatter light was integral with the solid angle of semi - globe space defined by the slope of the pixel , so scattering lights of terrain and the sky are properly considered , but the operation is still within the acceptable range
地形与反射率的关系是本文研究的一个重点。本文对崎岖山地象元的各入射光和反(散)射光分量进行了深入分析，在所提出的湿润土壤光谱模型和植被冠层模型的基础之上进一步提出了新的适合青藏高原的山地辐射传输模型。该模型同时考虑了土壤含水量、植被覆盖( lai ) 、地形起伏和海拔高度的影响，并以象元坡面定义的半球空间立体角对环境入射光进行积分，使周围地形和天空散射光均得到适当考虑，计算量又在可接受范围内。
