Abstract
A surface profile analyzer of the present invention is a device chiefly for analyzing the profile of the skin surface of a human. It has a ring-shaped illuminating device for irradiating a predetermined place of a test surface from all peripheral directions thereof, and an image pick-up device for photographing the test surface illuminated by the ring-shaped illuminating device. A digital signal generating device for converting the image signal of the test surface coming from the image pick-up device into a digital signal is used in conjunction with a computer to analyze the surface profile.
