1. An apparatus for in-vivo optical analysis of internal structures of a specimen of light scattering tissue by moving said apparatus relative to a surface of the specimen, said apparatus comprising:
- at least one light irradiating means for irradiating primary light into the surface of an in-vivo specimen;
at least one light detecting means for detecting secondary light from the surface of the specimen; and
displacement sensor means for sensing a relative movement between the light irradiating means and the light detecting means relative to the surface of the specimen, said displacement sensor means tracing a path on the surface of the specimen and sensing displacement when the apparatus is moved on the surface of the specimen; and
evaluation means connected to said light irradiating means, said light detecting means, and said displacement sensor means, said evaluation means processing data from said light detecting means and said displacement sensor means, and correlating the relative movement with said data from said light detecting means.

17. A method for in-vivo optical analysis of internal structures of a specimen of light scattering tissue, said method comprising the steps of:
-
irradiating primary light into a surface of a scattering in-vivo specimen with a light irradiating means; detecting secondary light emerging from the surface of the specimen with a detecting means; displacing said light irradiating means and said detection means relative to the surface of the specimen; sensing a displacement of said light irradiating means and said light detecting means with respect to the surface of the specimen with a displacement sensor means, said displacement sensor means tracing a path on the surface of the specimen and sensing displacement when the displacement sensor means is moved on the surface of the specimen; processing data from the light detecting means and the displacement sensor means; and correlating the data from the light detecting means and the displacement sensor means. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
