Abstract
The invention relates to a method and an apparatus for collecting structural data with spectral optical coherence tomography from samples having a point of maximum reflectance. This point of maximum reflectance is used for adjusting the scanned path pattern.
Claims15
Method for collecting structural data with spectral optical coherence tomography from samples (12) having a point of maximum reflectance comprising the steps of
- a) performing a set of at least two B scans along at least two scanning lines (20a, 20b, 21a, 21b, 22a, 22b) which scanning lines (20a, 20b, 21a, 21b, 22a, 22b) are linearly independent and intersecting at a point of intersection;
- b) identifying the maxima of light intensity along said scanning lines (20a, 20b, 21a, 21b, 22a, 22b);
- c) determining the offset of said maxima from said point of intersection;
- d) re-performing steps a) to c), whereby the position of at least one of said scanning lines (20a, 20b, 21a, 21b, 22a, 22b) is changed and the point of intersection is adjusted in dependence of the result of the determination step c).
