A new linear coded profilometry,which uses two phase opposite linear grate lights and one homogeneous light,is presented.By three time measurements,we can obtain not only the shape of the object,but also the surface texture.When the background light is dark enough,the shape of the object can be obtained by two time measurements.Though theoretical analysis,the precision with this technique is almost one time higher than the linearly coded profilometry with two half period phase shifting grate lights.
