Abstract
We have performed several original experiments, in order to investigate the nature of optical interference. In some contexts, the assumption that light beams suffer perturbations during their interaction is the most plausible. In others, the assumption that they do not is more appealing. Yet, the observable outcomes of both models are compatible with each other, in theory as well as in experiment. We conclude that they work equally well for the purpose of making physical predictions, and that each of them is logically valid. However, their interpretive value is not equal. If we assume that light beams cross each other unperturbed (even at the microscopic level), then we run into theoretical complications and even paradoxes that are not otherwise present.
