立体角

Analysis of Spot Size and Solid Angle on an Optical System by Ray Tracing Method.

运用光线追踪法於光学系统的光斑与立体角分析。

As is known in the art, etendue is a function of the area of the emitting source and the solid angle that the light beam includes.

如在本领域中已知的那样，光学扩展性随着发射源的面积和光束所成的立体角而变。

This is in contrast to a light source such as the incandescent light bulb, which emits into a large solid angle and over a wide spectrum of wavelength.

这是对比的光源，如白炽灯灯泡，该物质为一体的大型立体角，并在很宽的光谱波长。

Luminaire using reflection and/or refraction to increase the luminous intensity within a limited solid angle.

在限定的立体角内采用反射或折射法提高光强的灯具。

The array covers geometrically 85%90% of the 4π solid angle with low detection thresholds.

总立体角覆盖约全空间的85%90%，以及有一个很低的能量探测阈。

The numerical results show that a reasonable reconstruction is also possible for low wavenumbers even when the incidence and observation aperture is as small as the possible π/4 solid angle.

数值结果表明，对较小的波数，即使当入射和观测孔径为π/4立体角时，得到一个合理的重构也是可能的。

It is shown that the light intensity after solid angle revision does not vary significantly from one geometry to another.

结果表明，经过立体角修正后得到的磷屏影像光强度与测量几何条件无关；在磷屏未饱和的前提下，磷屏影像光强度与磷屏受到的辐射成正比。

In this work, a single Fe atom and multi Fe atoms as model respectively, holograms recorded in a complete 4π solid angle with different range and magnitude of incident energies are calculated.

分别以单个和多个铁原子为模型，数值模拟了它们在4π立体角范围内、不同范围的入射能量的情况下记录的全息图。

Based on the Mie scattering theory, a formula to calculate the scattered light flux in a certain solid angle under the condition of polarized light input is derived form the formula for calculating scattered light intensity. The results are compared with the condition illuminated by a unpolarized light.

在Mie散射理论基础上，由单分散射的光强表达式导出在偏振光的入射条件下一定立体角内的散射光通量的表达式，并与自然光入射作比较。

By employing the Cubist interlocking of angular, fragmented planes, Boccioni creates, not the homogeneous glitter of Impressionism, but a dissonant joining and separation of forms almost audible in their clangorous reverberations.

采用立体角联锁、零散机 boccioni造成，而非齐忽闪的印象派、但加入了调分离方式几乎可听见他们响亮回响。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
