摘要： PROBLEM TO BE SOLVED: To eliminate the need for a driving mechanism which scans an optical path by wavelength variation of a light source and speed up the scanning by using a variable wavelength type light source as a light source and adding a spectral element to an optical system. SOLUTION: The variable wavelength type light source is used as the light source 10 and the spectral element 50 is added to the optical system represented by a lens 30. The variable wavelength type light source 10 can be varied in wavelength continuously or stepwise. The spectral element 50 is an element which shifts in optical path with the wavelength and placed in front of an image pickup element 40. Light 12 with short wavelength travels as shown by the broken line after exiting from the spectral element 50. Consequently, the right part of an array in an enlarged image is observed. Light 12 with long wavelength travels as shown by the dotted line after exiting from the spectral element 50. Consequently, the left part of the array in the enlarged image 22 is observed. Light 12 with intermediate wavelength travels as shown by the solid line after exiting from the spectral element 50. Consequently, the center part of the array in the enlarged image 22 is observed. Thus, the whole fiber image 22 can be observed.
