Show affiliationsA concept of 'particle detector' is presented and found to include a variety of different possible models. A method of comparing these different models is introduced and a concept of 'particle detector equivalence' is defined. This concept is then applied to three different detectors of the neutral scalar quantum field. It is found that these detectors, in general, are not equivalent in that they will perceive a different particle content when placed in identical situations. These results are consistent with the Copenhagen interpretation of quantum mechanics. The equivalence concept is also used to construct several theorems which may be useful in gaining some insight into possible symmetries between fields of different spin.
