Adapted illuminations for indoor cultures
Here is a concrete application example of the reflector problem. The goal is to transform a random source density of light into a uniform illumination, in the context of indoor culture.
The source is colinear and its support is circular, the target is rectangular and the desired illumination is uniform. According to the notations introduced in the PIR0 configuration schematic, the following examples will be executed with the following parameters:
-
Theoretical case
Let us first consider the source density is uniform. A first calculation of the reflector shape leads logically to a uniform illumination of the target.
-
Practical cases
In practice, the source density is not uniform. Let us assume that the real source density is gaussian and that we use the same reflector as in the theoretical case. The result would be the following:
In the case of even more disturbed source densities:
-
Reflector correction
Source density profile beeing known, we are able to adapt the reflector shape in order to get an effectively uniform culture illumination.
