Patent ID: 7872754

Claim:
An optical measurement device for measuring an optical appearance of a surface of a sample ( 12 ), in particular the surface ( 14 ) of a human skin, wherein the optical measurement device comprises: a first illumination device ( 16 ) for illuminating the surface of the skin ( 14 ) with a first illumination beam ( 22 ), wherein the first illumination beam ( 22 ) is incident at a first angle of incidence ( 38 ) onto the surface ( 14 ); and a detection device ( 28 ) for detecting a response beam ( 42 ), wherein the response beam ( 42 ) is a response of the sample ( 12 ) to the first illumination beam ( 22 ), comprising at least one screen ( 27 ) for intercepting the response beam ( 42 ) and at least an image detection component ( 29 ), characterized in that the optical measurement device ( 10 ) comprises a second illumination device ( 18 ), wherein the second illumination device ( 18 ) is providing a second illumination beam ( 24 ) with a second angle of incidence ( 54 ) at the surface ( 14 ), wherein the first angle of incidence ( 38 ) is different from the second angle of incidence, further characterized in that the screen is a full hemispherical screen, intercepting the response beam in about 360 degrees above the surface of the sample.
