2.2.1. Solar image in the focal plane from ray tracing software
To obtain the solar image in focal plane from ray tracing software, it is necessary to create solid models, either by the same software or by any computer aided design (CAD) software. Once in the optical modelling software, the portions of the rays of the light source propagate with the flow of light, in accordance with the properties assigned to the relevant objects, which include absorption and reflection. The sources of the light rays or grid rays involve the system characteristics, as in Ref. [12]. Fig. 3 shows the ray tracing simulation for the study case.
