Beyond the diffraction limit: Super-resolving pupils

In an attempt to transfer the results obtained with super-gain antennas to optical systems in order to increase the resolving power, an original way for overcoming the diffraction limit was proposed in 1952. In this work, we report on the results of microwave experiments which demonstrate the correctness of these predictions. Their interpretation in relation to the uncertainty principle is then discussed, and a possible connection with the “weak measurement” theory is then suggested.
