Re: which law of physics is broken

When using a radio array or microphone array, there is no antenna. The array elements capture the wavefront amplitude/phase, and a virtual "lens" can be constructed, although it seems that non-linear and signal-adaptive signal processing is often preferred.

What is the fundamental physical limit that tells us this can never be done in a camera? I.e. a bare naked image sensor where each sensel not only integrate power to find light energy, but record the actual electromagnetic waveform? Once you get into the nitty-gritty single-photon-counting business, what is the fundamental difference, really?

Although such a sensor is probably technically impossible today, and although it would still have access to a finite amount of information describing the scene, the possibility of choosing your optics _after_ having shot the scene, plugging in optics that are impossible to construct physically (or economically non-viable), ones that distort to follow your goals with a certain scene sure sounds intriguing.
