A rod type waveguide sensor of the present invention, formed of a shape of a rod, and comprising: a rod portion which delivers a first signal inputted to a first position to a second position; and a generation portion which generates a reverse signal of a second signal outputted from an interface of the second position. The second signal is a noise signal having a noise added to the first signal within a process of delivering the first signal from the first position to the interface of the second position. The reverse signal may be the first signal, when the reverse signal is inputted to the first position and outputted to the interface of the second position. |
