Say I have a light source at a distance of 1Km from a light detector (photo detector). Right in front of the sensor, I keep a rotating reticle with some sort of pattern.
To better appreciate the situation take a look at the image below.
Now I want to simulate the detector output signal for various patterns on the reticle. For example "reticle B" from the above image would produce a square wave, and the "reticle A" would produce a pulse train.
Is there any tool for doing such kind of simulation? Is there any python/matlab library?
