Are interaction-free measurements interaction free?

In 1993, Elitzur and Vaidman introduced the concept of interaction-free mea surements, which allowed finding objects without "touching" them. In the pr oposed method, since the objects were not touched, even by photons, thus, t he interaction-free measurements can be called "seeing in the dark." Since then, several experiments have been successfully performed and various modi fications were suggested. Recently, however, the validity of the term "imer action-free" has been questioned. The criticism of the name is briefly revi ewed and the meaning of the interaction-free measurements is clarified. (C) 2001 MAIK "Nauka/Interperiodica".
