My goal is to build a software program that simulates the function of the eye. As I (barely) understand things, a single photon can bounce off an object and enter my eye.
Q1 - Does the photon determine the color? If not, what determines the color of that single wave/particle?
Q2 - How many photoreceptors does a single photon influence? And to what degree?
Where I'm at in my understanding: I believe we can calculate how many photons a certain light source gives off, thus we can determine how many photons can enter through the pupil knowing the necessary variables (distance, etc.). But imagine we have a light source that emits just one photon in the perfect trajectory to bounce off a flat wall and enter my eye. How many photoreceptors would that single photon impact/influence? In other words, the dreaded question is: what size (how big) should I calculate a photon to be?
Q3 - Won't I also need to determine the exact path and angle through the pupil in order to know WHICH photoreceptor(s) are impacted by a single photon?
**
I'm not looking for a science lesson here. I realize a photon can't have size, but at the same time it does have measurable properties. Perhaps my terminology is off and if we replaced "photon" with "light ray" you could provide a better answer for me. I use photon because the energy level can be quantified and that energy should help me determine if the opsin is sufficiently excited (cones need more, for example).
I guess I'm hoping for some "in the ballpark" guesses. Or an attempt to have me look at the problem for a different direction.
In the end, I need to the guidance that will result in a software simulation of the operation of phototransduction.
Any thoughts?
Thanks,
Kerry
