Abstract: The object of the invention is to provide a favorable spectral characteristic that reduces variation depending on the frequency of received light intensity, and that is gentle on a subject eye. It also eliminates displacement between positions of respective spectral images of the same part even if a change in alignment occurs between the eye and apparatus with the lapse of time.

Abstract: A three-dimensional coordinate measuring apparatus has a first and second incident angle adjusting sections for adjusting the attitude of the object in the directions of first and second neutral axes, respectively, to adjust the incident angle of the beam projected on the object from an imaging optical system relative to the object so that first and second stereoscopic images of the object can be formed, a matching process section for searching for corresponding points corresponding to measurement points in first and second search directions generally perpendicular to the first and second neutral axes, respectively, in the first and second stereoscopic images, and a shape measuring section for obtaining three-dimensional coordinate data of the object based on the relation between the measurement points and the corresponding points in the first and second stereoscopic images.
