In the process of trying to understand holography I encountered a detail that I kind of knew before, but just now I realized I have no idea how it works, how is it even possible. I’m talking about a simple pinhole camera where supposedly no matter how tiny a hole is a beam of light would still contain all the information to construct a picture of the whole visual field.
- Am I mistaken in some way that a lense is actually necessary to obtain full information from the scene?
- Where is the limit, just how narrow a light beam can still contain all the information from the scene?
- What defines the resolution or amount of information in a light beam relative to beam width?
- If apparent from these questions, where exactly is my confusion, what did I miss or forget?
