IMAGING OF BURIED STRUCTURES

摘要

A method of obtaining an image of buried structures in an object, comprising partially irradiating said object by light of a wavelength that images said buried structure; and obtaining a complementary partial image of said buried structure by light diffused from a non-irradiated image area. According to the method, an image can be obtained while discarding specular reflections of the object. Thus, deeper structures will be better visible. In a further aspect, the invention offers a method of enhancing imaging of buried structures in an object, comprising: analysing said image as a first image in order to detect the edges of said buried structure; obtaining a second image by irradiating said object with a second light that visually images said object; and combining said first and second images for defining edges of said buried structure in said visual image.
