PROBLEM TO BE SOLVED: To provide a method for precisely and easily measuring the state of a skin surface including minute unevenness, and rapidly obtaining a result.SOLUTION: The uneven state of a skin surface of a person is measured by analyzing point group data of the relative heights of reflection positions obtained by continuously performing a procedure of measuring the relative height of a reflection position by directly irradiating white light on the skin surface of an subject through an axial chromatic aberration-equipped objective lens L or irradiating the white light on a replica P created from a measurement target region of the face of the subject, making reflection light be reflected on a half mirror H through the same lens L, thereafter making an image be re-formed, and selectively detecting a wavelength component of the reflection light forming the clearest image while moving a light source S performing the irradiation or the position of a specimen in an optional back and forth and right and left direction.COPYRIGHT: (C)2013,JPO&INPIT【課題】微細な凹凸を含む皮膚表面の状態を精密に且つ簡便に測定し、迅速に結果を得る方法を提供する。【解決手段】白色光を軸上色収差付き対物レンズLを通して被験者の皮膚表面に直接あるいは被験者の顔面の測定対象部位から作成されるレプリカPに照射し、反射光を同じレンズLを通して、半透鏡Hで反射させた後再結像させ、最も鮮明に結像する反射光の波長成分を選択的に検出することによって反射位置の相対高さを測定する手順を、照射する光源Sもしくは検体の位置を前後左右任意の方向に移動させながら、連続して行なうことにより得られる反射位置の相対高さの点群データを解析することにより、人の皮膚表面の凹凸状態を測定する。【選択図】図2
