<p>It is possible to provide an excellent rotary body measuring device which can appropriately observe and measure a target position of a rotary body from a necessary direction by using a simple configuration. The measuring device includes: an optical system (OP) having an objective lens (1) at the tip end and a half mirror (2) as a light guiding unit at an intermediate portion; a camera (3) as image acquisition means optically connected to a base side of the optical system (OP); and a blinking light source (4) arranged to introduce the blinking light (X) to the half mirror (2).The blinking light (X) from the blinking light source (4) is outputted from the tip end of the optical system (OP) via the half mirror (2) and applied via a space to a rotary body (R) in rotation as a measurement object. The blinking light (X') reflected is acquired by the camera (3) via the objective lens (1) and the half mirror (2) of the optical system (OP) so that the rotary body (R) in a virtually stop state can be measured.</p> |
