A light divider separates pulsed light emitted from an ultrashort pulse fiber laser into reference light A and signal light. A scanning mirror unit irradiates an object with the signal light and receives scattered light B, which is reflected from the object.

A differential detector detects the degree of interference of the reference light A having the adjusted optical path length with the scattered light B and outputs the detected degree of interference as an interference signal. A computer specifies an adjustment value, set in the optical path length adjustment unit, to attain a specific optical path length maximizing the interference signal and uses the specified adjustment value to compute the distance from the scanning mirror unit to the object.

When ultrashort pulsed light is introduced into an optical fiber (3), a wavelength-tunable ultrashort soliton pulse is generated by a nonlinear optical effect through the soliton effect and Raman scattering.

This third harmonic has a short wavelength in the visible light band.
