検出装置。An inner peripheral surface state detection device for detecting the state of a cylindrical inner peripheral surface formed by a drilled hole, the device comprising: a cylindrical sliding body slidably inserted into the hole; 1; the cylindrical sliding body; a cylindrical lens mounted inside a moving body and converting an incident light beam into a parallel light beam; a conical prism that is mounted inside a cylindrical sliding body and that reflects a parallel beam from the cylindrical lens in a radial direction of the cylindrical sliding body; and a first optical fiber that causes a light beam from a light source to enter the cylindrical lens. a light separation means provided in the middle of the first optical fiber to transmit the light beam from the light source and reflect the reflected light beam from the cylindrical lens; and a light beam reflected by the light separation means. and a second optical fiber that guides the charge conversion means to a photoelectric conversion means, and detects the state of the cylindrical inner peripheral surface based on the output of the charge conversion means.
