Thomas,
Theoretically, the sensor indeed needs to be at least twice the
largest wavelength it's supposed to capture. However, two more
factors favour a sensor sized to at least an order of magnitude
above the wavelength:
- diffraction in the optical path;
- light propagation under the sensor surface (we assume
the sensor is not under its own lens - this would further
increase its minimum size).
