Abstract

There is provided a surveying instrument including a distance measurement arithmetic module configured to measure a distance to an object and the reflection intensity of a reflected distance measuring light based on a distance measuring light and the reflected distance measuring light, a narrow-angle image pickup module configured to acquire an image with an axis of the distance measuring optical as a center, an optical axis deflector configured to have a wavelength dispersion compensation prism arranged in the distance measuring optical axis and deflect the distance measuring optical axis by the rotation of the wavelength dispersion compensation prism, an extracting means configured to extract an end face reflection image of the wavelength dispersion compensation prism from the image, and an arithmetic control module configured to calculate a deflecting direction of the optical axis deflector based on the end face reflection image extracted by the extracting means.
