The new sensor just does not seem to get anything. As before, everything is brilliant on lens+palm system, but des not work completely with the real eye. Something must be completely wrong, I have no idea what exactly =(
Update: there might be a small chance that some of the structures of the eye that are transparent to visible light are not transparent in the near infrared that I'm using. Or the infrared light is not backscattered by retina. So, I'll probably try making a sensor based on visible light.
Anyway, I wont be able to work on the project during next week, but I'll continue thinking.
