In this paper, we used the method of ray-tracing simulation  and the solar cell circuit network model [12-18] to analyze the illumination distribution and the power performance of the solar cell at different positions of the optical axis.
If the illumination distribution of incident light is uniform, it is also uniform for the light of a certain wavelength on the receiving surface, so that the illumination energy distribution of the receiving surface can be calculated.
It can be seen that the illumination distribution of different wavelengths of light is generally different and the range of illumination is also different, so the illumination distribution on the receiving surface must be nonuniform.
We have known from Figure 8 that the refractive indices of different wave bands of sunlight are different, so the illumination distribution of different bands in the optical axis will be different.
By reconstructing the illumination distribution of a scene, we can project realistic virtual shadows of a virtual object onto the real scene.
described a method to recover an illumination distribution of a scene from image brightness inside shadows cast by an object of a known shape .
This paper presents two novel AR methods to estimate environment illumination distribution. By using an orientation sensor of a mobile device, we extract the lighting direction and intensity from input images captured with a front-side camera.
The elements are fully optimizable; for example, users can automatically optimize a CPC's size and angle to match a target illumination distribution
, intensity, total power or flux on a receiver.
The fixtures had to be positioned out of the path of traffic, yet still achieve the proper illumination distribution
for driver comfort and safety.
The illumination distribution incident on the cell surface in a concentrator system consisting of reflective troughs is highly non-uniform and takes the shape of a Gaussian profile .
