Abstract
A vibration sensor is provided in a telescope. When vibrations are detected by the vibration sensor, the vibrating state of a reflecting mirror is estimated by the vibration sensor. When an image signal is captured by an image sensor, the frequency or period of capturing the image signal is varied depending on the state of vibrations of the reflecting mirror. In this manner, the time required for measurement is shortened, or the measuring error due to the swinging of the reflecting mirror is minimized.
